I have answers to several questions. They cannot be bridged mono, just buy some monoblocks soon available. There will be a pair of them at the RMAF. They are 30 watts cont., 60+ watts for a few seconds if needed! Yes, I am using the same basic circuit I used in Scotts Eico's. Actually it would take a lot of red tops to weigh in at 275 each amp, but boy it sure would play a long time!
When I first turned on the first amp , I used only 1 battery like the ones in the battery preamp and it played for 50 minutes before it faded away. 1 battery 1000 batteries it is always 15 watts per channel cont.
NO pics of the inside will be shown ever. Believe me i have it protected just like the battery preamp, no one needs to know, just enjoy it and wonder.
