Having played with the small 9302 Magnavox 6BQ5 PP stereo amp for awhile, I've caught a second case of tube amp syndrome. I heard of another Magnavox tube amp used in Imperial and Concert Grand. Amp model is AMP-148. For those that don't know it's a bi-amp monoblock using six 6v6 PP for the lows (35w) and two 6v6 PP for the highs (15w), two 5u4 rectifiers, and two other 9-pin tubes probably 6EU7s.
I intend to find a pair of these (one already found) and make one large stereo (dual-mono) amplifier chassis out of it.
Any of you guys care to suggest some layouts based on the photo below?
Total chassis mounted parts count:
2 - large power transformers
2 - large output transformers
2 - small output transformers
16 - 6v6 output tubes
4 - 6eu7/12ax7 for pre. and phase inv.
4 - 5U4 rectifiers
6 - capacitors
