I'm still not happy with the way this little 6V6 amp in this Hoffman Super Receiver Mark V underperforms, hardly 10w, if even that, and with distortion.

So I'm gonna do something a bit off the wall.
Last week, I got one of my old Dynaco mark iii monoblock amps out of storage and got it working, did not take much, just had to replace the main milti electrolytic capacitor, all other parts were still good.

First test.

Will do a full blown test with large speakers this weekend.

Hooking it to the Hoffman should be rather easy.

Remove V31 in Hoffman amp, use old dead tube's plug to adapt to socket to make coaxial cable going to pin 1 and ground with rca connector for Dynaco input.

I foresee no problems other than finding a speaker big enough to take 60w!
