I built one of these amps using the Siliconray boards some years ago which hasn't been used. I recently ran it for a few days and had problems with the L channel blowing the pcb fuse. Having checked it over it seems that I can't now get the dc offset down and my light bulb tester is glowing brightly when the L channel only is connected (dual mono double psu design)

I Built the board using TIP3055 transistors. My electronics knowledge has increased a little since I built that amp and I have a few questions I wonder if anyone can answer.

I used the TIP 3055's in both positions on the board, but now wonder whether they should both be the same or whether one of them should have been a P channel 2955. I am probably going to replace all the output transistors on both boards and wondered which ones would be favourite for the board's interpretation of the JLH amp.
