Fisher turntable and TX-300
#23

Yeah...maybe back then.....(I did not imply DC cap saves it though, it does not even matter,simply allows unipolar DC amp to drive low ohms load) ....

I built two Ge transistor amps, the first being transformer output pushpull on Soviet P210

(the largest Ge transistor at the time....well, the biggest of all times were P207-P208 but they were discontinued by that time)
http://www.155la3.ru/p207.htm
Behold. 74мм flange. The contacts were so this when one broke it was possible to drill in it, tap a thread and put a screw in. A 25A capable device, in those times.

Another was your regular pushpull with DC blocking cap on P215

These are smaller, about 10w dissip.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
