Hi Apex audio. Can I change amp this to a 2 step version with 150v and 75v rails ? I have just got a 3.5kva transformer with 53v windings x 4. Can I just leave out the lower voltage stepper ? and do you think this will affect the efficiency much.

Thanks for all the work your have shared.

Hi wiljj78, is it possible for the 4 driver transistors(mje15034/35) in the middle to be fix in the main heatsink under the board?

regards,
mj777
