  1. Interesting! They all sound different but I couldn't say which I thought sounded the best. When I got my MB 801 I also tried the PJB Double Four. Although I fancied the PJB's portability (you can run it form an external laptop battery pack) the MB just sounded fuller in the bass and 'bigger'.
  2. Well I'm glad I found this thread. My usual practice amp is a Markbass 801 combo, which although remarkable for its size is not especially inspiring. Given that it's going to be months before I stand on a stage again, I dived into my kit cupboard and came out with my One 10 and Demeter head. These are now installed in the 801's usual spot - now we're talking! EDIT: It made me want to play bass for longer. Result.
  3. Absolutely! The One 10 has a lovely rich vintage sound. I used mine with an Ampeg PF50T to great effect, and according to www.disssa.de the PF20T has a lot of the B15 vibe going on. (But be aware that some of the early models of these amps reportedly suffered from hum.)
  4. Hell yeah!
  5. I’m planning to build a B15-type amp in a similar cabinet. That will challenge my woodwork ‘skills’!
  6. A bit like this then:
  7. @PeteJ just wondering why you would want to do this rather than just transport the lightweight head in a suitable case and take it out to use.
  8. Adam bought an electro-classical guitar from me and worked with me to make the deal happen. Thanks Adam!
  9. That’s great, there will be a lot of people here who appreciate that.
  10. Update - EBS did reply, and gave me the full spec of the capacitor. I have bought a couple in case I do need to replace it. Amp sounded great at the Bowie tribute rehearsal. I got the full rig out again yesterday and played my Dingwall PZ5 through it, now fitted with rounds (Elixir Nanoweb). That is one quality sound!
  11. Yes I have. I plan to build mine from scratch though!
  12. I'm gravitating towards the earlier preamp and the grid biased power amp. I've never found much use for the Ultra Lo filter either but some kind of bright switch could be useful. It will only take a couple of extra components to provide the cathode biased option, so I'll probably include a switch for that on the rear panel.
  13. Still waiting for someone (anyone!) to comment on the pros and cons of the different B15 models...
  14. @agedhorse - to be fair, @Hellzero does mention a resistor for discharging caps.
  15. Well I found this video comparing a 1963 B15N and a 1971 B15S. They both sound great but they are running through different cabs:
  16. Cheers chaps. My last PP amp build was the Trainwreck Rocket, which is a stripped-down AC30 top boost and uses a long tailed pair PI.
  17. I looked at the SB12 schematic (see below). The preamp uses 12AX7s but I fancy doing a build with octal preamp valves. Just out of interest, is there a name for that phase inverter arrangement?
  18. Yes, the only place I see the old metal ones is on restorations by Uncle Doug on YouTube!
  19. Quite right, like many people I just say 6L6 when I mean 6L6GC.
  20. For whatever reason my bass tastes rarely seem to coincide with yours @Cat Burrito but that all changed when I saw that Burns!
  21. I think this is what they call the nuclear option!
