RE: Beveridge?

I have flirted with the idea of talking to Modjeski, and now you mention it, I don't remember what became of that conversation. I don't think he was willing to build a direct-drive amplifier de novo at that time. The OEM Beveridge amplifiers develop +/-1600v, or 3200V if you're a lumper. So, when you say 2kV, do you mean per phase or total from plus to minus?

I was lucky to find a guy on TubeDIY who also has 2SWs and is an EE. He walked me through trouble-shooting my amplifiers and from him I learned a lot about their care and feeding. I also learned the hard way that 1600V can jump a gap, into my finger tip from 3-4 inches away. The solid-state input and driver stages could probably be done better these days, but even he (my EE penpal) is loathe to do a re-design. Is Modjeski using all tubes now? Interestingly, inside each of my two amplifiers, you can see his signature in magic marker, dated 1979. Kind of like the Futterman H1 signed by JF.

I think what happened was I did not want to lose use of my speakers for the time it might have taken for RM to revamp the amplifiers. On the subject of bass response, the KEF B139 in TL does a great job of keeping up with the panels around the crossover point, but in my rather large finished basement, extreme low bass is not fully "there". I could indeed use a subwoof.
