Frankenstein Amp to be "born"

It has been one year today since I last posted. Since then some caps on the Carmen Ghia have started leaking and producing awful noise. That project will be this summer. Now I am designing a "new" amp to be made from the main amp (model 6026) that came from the Conn Model 542 Minuet organ. What I hope to do with it involves adding a single preamp to drive the two power amps in parallel. The twist is that I hope to tie the two output transformers in series on the secondary side. Schematics will get worked out before November this year. I probably won't finish this until 2014.

Thanks for doing this. I have been waiting for you to post your schematic with the preamp.
I have 2 of these amps and was thinking of leaving them stereo and ad a couple 6U10 compraction tubes for the preamp sections. These guys are 3 triodes in one envelope with 3 different ways you can hook one up in series, you could even rotate the preamp tube with a selector if you wanted different preamp sounds. They look like they might be fun to work with. Regards, Tom pathtologic@gmail.com
