I have this 1950's PA amplifier that have been waiting to be used for something. I've decided to change it to a stereo hifi amplifier to test my latest C-core output transformers. I took some photos before I stripped the amplifier.
I do not have photos of the amplifier outside. This I got from the 'Net
The inside is very beautiful:
Microphone inputs
Here is the bias supply
ECC40 gain stage
More of the same with the phase splitter in the foreground
The EF86's have been removed. A shot of the power supply arrangement:
Power amplifier coupling caps and grid leak arrangement
That's it folks!
