  1. [quote name='funkle' timestamp='1474481571' post='3138342'] What's the ideal power for an F112? What is the max anyone has pushed through it? Edit: It's just I see people using very big power amps through these...and the 3012LF is a power hungry driver...is there a micro amp with 'big' power? [/quote] You need to look at 8 ohm power ratings. IME 600-800 watts works about right, but I'd shoot for at least 450 if trying to maximize output capabilities. The GK MB800 series is fairly popular with that crew, for one.
  2. I ended up doing a second one of these for a friend, using the original prototype enclosure that didn't quote meet my specs. The fabricator let me keep it at no charge though, since it wasn't going to do them any good. My friend had the half rack format preamp and power amp I built last year, but decided that an integrated amp just makes more sense -- the same reason I got rid of the 1/2 rack stuff in the first place. So I traded back the pretty nice sounding 1/2 rack stuff for a build with the "bummer" case and the the guts pictured above. This of course gave me a perfect excuse to work on rev. 4 of my preamp and HPF/PEQ boards, which I have just finished up. Among other things, I went a little deeper down the rabbit hole with an even more uptown Jensen input transformer for the power amp section, and a hybrid dual opamp that is 1/2 FET input and 1/2 bipolar. Those little SMD/DIP adapters came in handy for that. So, the new one for my friend, note the unwelded case seams: And my own, with what passes for a pink LED pilot light: The 1/2 rack format pair: And finally, the original rack mount one, which uses an older ICEpower 500 watt module: Time to move along to some simpler and more economical builds for a while now, I reckon.
  3. [quote name='Subthumper' timestamp='1474106908' post='3135634'] Ok will do. I've got a few other projects on the go so will be a little while until I do it but keep an eye out. I'm thinking model T preamp split channel with a bassman preamp. Not so much drive and clean but two distinctly different sounds. All mated up to a 4x kt88 power amp. What ya think folks? [/quote] Sounds cool, always liked the Model T. I'm going to take another swing at redoing my 80s Fender 30 combo one of these days, although its current quasi-single channel Vibrolux Reverb format is actually pretty danged sweet.
  4. [quote name='MacDaddy' timestamp='1474317804' post='3137151'] Blue, if that post is a genuine reply to mine, then I have to say you are propagating the belief that American's do not understand irony. [/quote] Well, not in Milwaukee anyway.
  5. [quote name='Marvin' timestamp='1474373805' post='3137454'] It did its job well, maybe too well. Schroeders (the earlier ones) don't focus on deep bass tones, but then I've always rolled them out anyway so not a problem for me. [/quote] Depends on which early ones you mean. I had a 1210L that was all mids all the time, and then a 21012L that made tons of low bass and was pretty well balanced all in all. The 1210L was fantastic for one particular band situation at the time, but utterly hopeless at taking EQ if any other thing was desired. OTOH, the 21012L was great as long as you didn't ever have to move it. I never see Schro cabs around here any more though.
  6. [quote name='Merton' timestamp='1463302281' post='3050222'] 12", 6" mid and horn I believe [/quote] That's the fEARful line, the FEARLESS (sic) ones use a 5.
  7. [quote name='B.Flat' timestamp='1473797458' post='3133259'] This is my third attempt to obtain some info. Quite some time ago Uncle Fluffy put out some really good pcbs for home-build S'ray preamps, I bought three. I had fun installing them in my basses. Those basses have now found new homes. I am now trying to obtain one more board. I have pm'd Uncle F. but received no reply. Has anyone out there got one of these boards they are prepared to let go? If yes I would be so happy I would probably take the wife out !! [/quote] Please PM me and I'll see what I can do for you.
  8. [quote name='dood' timestamp='1473152501' post='3127334'] I've just been looking at your build thread. My reason for wanting to get hold of the Berg' B-Amp is probably the same as the functionality in your own design. A decent parametric and HPF really does make a big difference! Like your ideas, very tidy inside too [/quote] The B|Amp is a really nice piece and I found it to be one of the stars at NAMM this year. In the past I've done three different DSP based builds, including something a whole lot like a Bergantino IP amp knockoff. After some years of playing through through those rigs I settled on my current amp's feature set as a sweet spot for my particular wants and needs. My builds are modular and changing that feature set in the future wouldn't be terribly difficult if I become so inclined. Thanks for the kind words; in my mind I am just barely to the point of building stuff to something like a decent standard these days.
  9. [quote name='Chienmortbb' timestamp='1473078438' post='3126618'] The second operation was just as successful but other things have delayed the project. You may remember that I stated this thread when my wife was ill. She got progressively worse and I took on the role of full time carer. Sadly she died in June. I am still sorting out the many problems bereavement caused but I will be continuing the project soon. [/quote] As I've said in our emails, I feel deeply for you and will do whatever I can to make finishing up your build as smooth and fun as possible. I am just finishing up my 4th variation on this basic format, which happily will live somewhere else than chez moi. They all sound very good and I'm confident that yours will too.
  10. [quote name='sirmuppet' timestamp='1472481408' post='3121441'] Had a little search and couldn't find much. [/quote] Try 103 pages worth here: http://basschat.co.uk/topic/10285-show-us-your-rig/
  11. [quote name='[email protected]' timestamp='1472887902' post='3124999'] Very cool. How did you build the amp? Is it your own design? [/quote] There's a thread on the build here: [url="http://basschat.co.uk/topic/281844-a-diy-bass-head-build/page__p__3023103__hl__passinwind__fromsearch__1#entry3023103"]http://basschat.co.uk/topic/281844-a-diy-bass-head-build/[/url] I have a slightly revised version about halfway built sitting on my workbench at the moment.
  12. [quote name='Beer of the Bass' timestamp='1472848401' post='3124849'] Does the rectifier valve glow? That would be the simplest way to check. [/quote] Yep. That sounds very likely to be the problem, unless the filament supply has croaked on its own, which could have been the impetus for using the SS sub.
  13. Just added a DIY ramp to my Crescent Moon fretless: Which doesn't seem to make a huge difference, given my generally very light touch, but I do like the feel when I notice it.
  14. None of the usual suspects here: That's a DIY 650 watt head on an Audiokinesis Thunderchild TC112AF cab. These days I am mostly playing big band jazz shows on my BSX electric upright, or occasionally on my Crescent Moon fretless:
  15. [quote name='Chris Sharman' timestamp='1468883246' post='3094099'] Hi all, as per the title really, I am new to the EUB having recently taken ownership of an Eastcoast (rebranded Stagg I understand) and one of the bands I play for, Water for DOgs, have recently been exploring some more acoustic and chilled stuff using acoustics and piano. I would like to use my EUB on one or two tracks in a small scale live environment and I was wondering if anyone here uses a similar EUB in a small venue and has a recommendation for a suitable combo amp for the purpose. [/quote] Acoustic Image, especially the 210 model. Although if you're only going to be using the EUB for one or two tracks, it might be worth considering just going through the PA, assuming a decent one is in use. I've played quite a few open mikes and quickie sit-ins that way pretty happily with my BSX.
  16. [quote name='RickyV' timestamp='1469457815' post='3098438'] Simple question, for those that gig regularly, do you sit or stand when practicing at home?? [/quote] Stand, 99+% of the time.
  17. Google "light organ." Many pro lighting fixtures already have variations on this function built in..

    [quote name='KingBollock' timestamp='1467584967' post='3084736'] This is the only forum I am an active member of. It's home. And I am cripplingly shy (is one way to put it...). I was hoping to see what parts I have (I do build other things, I have just never worked with valves) and what I could scavenge. I have never had any interest in valve amps, but I would quite like a valve preamp for guitar. I have seen ones that look very simple, basic preamps with just gain and volume, but not much in the way of details (there is always either lots of pictures and no information, or lots said and no show, never both...). I figure that if I could get a plan, layout or schematic, and a bill of materials, with some general advice for the circuit, it would be enough to get me started. There is such a wide variety, I was hoping that someone here might give me a clue before I just close my eyes, spin around and pick one at random. I have read that working with valve amps can be dangerous, but I am a safe worker when it comes to electricity, and I don't want the poweramp, just the preamp. [/quote] OK, but how about a little more direction on whether you want clean, dirty, Fender, Vox, Marshall, and so on? The AX84 site I linked has full layouts and bills of materials for many different circuits that you could just omit the power section for. One dedicated preamp build that many people have started with is also detailed here: [url="http://www.dogstar.dantimax.dk/tubestuf/mctube.htm"]http://www.dogstar.d...stuf/mctube.htm[/url] . This uses a lower power supply voltage than many others, which may be a smart way to start out IMO. My tube bass preamps all use at least 300 volts DC, at which point decent test equipment and a little experience are surely helpful things to have. Another time honored way to get your hands dirty would be to find an old and/or broken guitar or PA amp on the cheap and hopefully make something useful out of it with minimal cash outlay. For instance, this one just needed a new input jack and it ended up being used professionally around Seattle for several years before I traded back for it:
  19. This is my Heritage H204D, fitted with a Roland synth pickup. The amp is an early 80s Fender 30, one of Fender's first channel switching all tube amps. Every few years I mod it one way or another, and it is currently wired like a blackface Vibrolux Reverb without the tremolo circuit.
  20. Very nice build! Looking forward t seeing how you do the front panel, as that often tends to make or break the overall perceived build quality. I have tried really hard to get away from using IEC inlets these days. The Neutrik Powercon is my current favorite, for a variety of reasons.

    [quote name='KingBollock' timestamp='1467547949' post='3084427'] I have been thinking about building a tube preamp for a while now, but I don't know where to start. I know you can get them as pedals but I have been unable to find a layout for one. I don't even know what section of BassChat to ask about it in, especially as it is for guitar not bass (my bass amp has a tube channel preamp, but I don't like it). I don't want to buy a kit because they're expensive and I'd like to spend as little as possible. At the moment all I need is a plan for the preamp part, I can figure out what eq stage to use later. The only requirement really, is high gain. Any advice? Even if it's just to suggest what sub forum I should ask this in (so I can blame you if someone tells me I've put it in the wrong place...). [/quote] Why limit yourself to Basschat when you are wanting to build a guitar widget? Here are a couple of useful sites to get you started: http://www.ax84.com/ http://www.valvewizard.co.uk/ A kit will actually very likely save you both money and many headaches if you are needing to ask where to start, IMHO. Here's a relatively inexpensive one: http://www.paia.com/proddetail.asp?prod=9210K&cat=14 Good luck, and have fun.
  22. [quote name='spectoremg' timestamp='1467385294' post='3083337'] They were definitely hefty. [/quote] Not the digital CGI ones. Analog dinosaurs were always more organic.
  23. [quote name='Mykesbass' timestamp='1466579105' post='3076854'] $5k wow! Puts Foderas in a whole new light. Will check out those Talk bass posts, thanks. [/quote] I would guess/bet that most of the ones he actually sold commanded less than his full asking price. FWIW, I saw plenty of various brand basses priced at >$10K at NAMM this year.
  24. [quote name='Mykesbass' timestamp='1466541914' post='3076709'] Yes, this was the interesting looking bit (very small print at the top of the website), and yes, very little sign of it being available anywhere. [/quote] There was one at the Seattle Talkbass get-together a couple of years ago. I didn't play through it myself, but I thought it sounded pretty good, as one would hope it should for the $5K asking price. Flea used a couple of them for a brief while as well. A friend of mine looked into investing in the company but eventually thought better of it after visiting with the owner. If you do a search on "Vetchking" on Talkbass you should be able to find posts by the company principal. His posting style was rather, erm, exuberant. I was once tasked with cleaning up the huge mess that the original company created for the stores I worked for when they went out of business without any provision for honoring all those lifetime warranties. The bass amps were mostly pretty solid, but the tube guitar amps were a whole different story.
  25. [quote name='goblin' timestamp='1466460717' post='3076071'] I'm pretty sure these have been around a while now. From what I can tell, Chinese manufacture and not a patch on the original stuff. [/quote] They are a low end house brand for Guitar Center in the US, have been for several years. For a time Guitar Center also licensed the name "Acoustic USA" to a boutique builder doing extremely expensive quasi-reissues of the old iconic ones: https://www.facebook.com/AcousticBassUSA/?_fb_noscript=1 . It seems unclear if they are actually still in business, I think.
