Or simply put a chip amp kit that works on that supply, 7293, 7294, 49810, and so on...+/- 40 is a little too much for the 3886...
This amp is built too late to have the slow homotaxial 2N3055. It has dip IC's and TO220 drivers. The main fault possible in TO3 would be darlingtons. Every popular TO3 after 1980 had Ft adequate to full fidelity.
The driver transistors could be ****, the vas transistor could be ****, the input IC could be ****. All <$1 parts.
With dual output transistors, the power supply is too potent to be serving an a IC amp. It is more in the class of a 100 w/ch up to 200 w/ch. Heat sinks looked adequate. Fine for living room use with a few fidelity tweaks. I've used a Peavey PV4 in my TV room, re-ecapped and more heat sink. Nice HDTV sound on some PBS shows now. I've upgraded a Peavey M-2600 with a better op amp for my music room. Was TL074, now ST33079.
