Post Subject: 50 watt class A, PP...Posted by Axel on: 8/19/2009

well fine, my X350.5 does 50 watt class A, and of course in push-pull. I use it with 120 watt max rated 3 way speakers of about 87 dB efficiency. You can see on the 350.5's centre instrument dial if you go out of class A. If I go out, I usually fear for my 8" bass drivers first so it actually NEVER happens during 'normal' listening.

Any tube I have heard trying to satisfy a 4 - 6 ohm box-speakers ~ 86 - 88 dB just doesn't get there without going soft in the bass, loosing some control. Some like this effect, I don't. That leaves horns --- and THEN we start talking issues aplenty.

4 to 6 way, phase tracking of each horn!? how?, active amping with 8 to 12 tube monos, just for a starter.
My Pass is pulling ~ 670 watt in idle and it's giving me heat exhaustion in summer, no way I'm gonna survive with a stack of tube monos. So, it's horses for courses and I try to get the best from what I can live with.
Cheers,
Axel
