LOL! Yeah a tranny would have been awesome. The Citroen is one of the guitarists. Decent for getting out gear from place to place though!

Ha, that's no problem. Thanks for the kind words chaps.

Hey Basschatters. We just received the final cut of our new music video. Would love it if you could have a look! [url="http://www.youtube.com/watch?v=6StToVgItyo"]http://www.youtube.com/watch?v=6StToVgItyo[/url] Boom.

I was rightly or wrongly comparing the delta 10's I have to the delta 15, I don't think I could bare to rip the Dominator to shreds, it means quite alot to me as i've owned it for 17 years. The delta pro seems like it might be the best bet in terms of the sound I would want to get, but if you think the Celestion Neo is the most promising, it might be worth considering? Might save my back a little bit too.... If you could model the eminence neo's, it would be most appreciated. :-) Chris

[quote name='Phil Starr' post='1054424' date='Dec 10 2010, 07:35 PM']OK the speaker is probably a bit over 8 ohms but not by enough to worry the amp. So we'll go for an 8ohm speaker. The cab will have an internal volume of about 45litres, a bit small for a 15. Its probably got a huge bass hump and doesn't go too low with the fitted speaker. Speakers that would work in your cab might be Fane 15-500 £68 small bass hump, f3 74hz 112db output Fane 15-400 £54 nearly flat 115dB f3 91Hz Celestion BN 300S (neo so light weight) £75 Small bass hump f3 92 Eminence Delta 15pro £74.96 3dB bass hump, pronounced midrange hump f3 73 Hz Interesting and possibly not unlike the original as new, though I'm guessing here. Eminence Delta 15A loud with huge midrange and bass hump, wild and wooly Up to 120dB f3 73Hz. I'd go for the fane 15-400 for a cheap uncoloured sound or the Celestion Neo. Both would match a drummer but might need a little help from the PA in a medium sized venue. The Delta might be enough on its own for small and medium gigs. There's other alternatives especially if you want to pay more. Prices are from Blue Aran. Blue Aran you owe me. When I was doing PA in the olden times the WEM PA anp was the most desirable thing going, 100W of pure transistor power and made for PA with a flat response instead of a borrowed guitar amp. Pink Floyd were so proud of theirs they put them on the album sleeve. Google Ummagumma[/quote] Hey Phil, That's a crackin' bit of info. Thank you very much. Your right, bit of a tiny combo to have a 15 inside. Also right when you said about it not going down too low... Packs a might punch, but not a low one! I've got two 10 inch delta's in one of my cabs, I like the sound that they chuck out... So I might go for one of those. They sound pretty decent on break up with my big muff and tech 21 xxl. Plus I'm a bit of an eminence fan boy. I've got my eyes on some lovely looking el84's at the tube amp doctor, some of their TAD matched ones. I'll get some pictures up when I get it all sorted out. Thanks again.

Right then, the Multimeter is saying 7.1 when I touch the speaker connections. (The amp is now in bits so the speaker isnt attached to anything)... So i'm assuming it's an 8ohm speaker as I've read that most 8ohm speakers measure at about 7ohms? Measurements for the cab are 23 inches high, 22 inches wide and 8.5 inches deep. Take 5 inches off of the height for the amp gubbins that should be inside the cab, as I've have taken them out.

Wow, thanks for the responses and the advice chaps. Much appreciated. I havent gotten round to measuring the inside of the cab yet. I was waiting until the Multimeter turned up and I could do both things at the same time. I'll post up my results when the pesky mutlimeter turns up! :-)

[quote name='bumnote' post='1052036' date='Dec 8 2010, 07:49 PM']Unlike transistor amps, providing the output from the amplifier is set to the impedance value of the speaker, you will get the rated output from the amp, it doesnt matter if its 4, 8, or 16 However, a valve amp must be set to the impedance value of the speaker, otherwise when a signal passes through it there is a real danger of damaging the amplifier. Therefore 'IF' it is a 6 ohm output and you connect a 15 ohm speaker, you will not get reduced output, you could very well fry the amp.[/quote] Crikey.... There isnt an impedance changer switch or anything... If such a thing became a problem, how would one change the impedance the amp was chucking out? Knock three times?

Hmmm, interesting. So if it had a minimum load of 6 ohms an 8 ohm speaker could be alright. I've got a multimeter in the post so will find out for sure after i've had a play around. Will post up my results!

[quote name='umph' post='1049767' date='Dec 6 2010, 07:49 PM']schematic says 12ohms[/quote] Have you got a schematic for a Dominator 45 Bass? I'd love to get my hands on it if you have.... Could I ask if you would kindly send it to me please?

That's cool. It's difficult to try out new gear when you live quite far away from a decent music shop.... Youtube misled me and made me believe that a Line 6 HD750 was good..... I sent it back and bought a Markbass.

Thanks for that info, Phil. I'm very green to this, but would like to learn as I find it all very interesting. I would like to enhance the Dominator as much as possible really without ruining it, full of beef, with a hint of chardonnay. I've been putting together a shopping list on tubeampdoctor.com New matched valves, pots and caps. Anything else you can suggest that I should look in to changing/upgrading?

Thanks for the advice chaps, it all seems good. I did hook the dominator up to my 8ohm 4x10 cab and it sounded pretty rippin', not to say that this is the right impedance though!... I'll have a look at the output transformer to see if it can give me a clue, then ring watkins if I don't find anything.

Hey Basschatters, I wondered if I could pick your brains!?! I'm in the process of putting a shopping list together to do a bit of a restoration of my old WEM Dominator 45 Bass. It's a 15" combo with 4x el84's and 3x ecc83's. The old Fane speaker looks and sounds a bit naff and I was going to replace it, it doesn't say whether it's a 8 or 16 ohm speaker and I can't find any solid conformation to say which one it is. I also don't have the means to test the speakers impedance. Anyone got any idea what I should purchase? Thanks in advance for anyone's advice.

Nice job on this Truckstop. Keeping the spirit of Basschat going!

Sounds like a great idea. I could do with one of these! Count me in please, kind sir!

Someone get Toca 2.... Old fav of mine! bleddy wicked!

I'm all over this... Might put it on my facebook and get people to watch it....

I've had a few of these. Cracking bit of kit!
