Can anyone direct me to a schematic for a Heathkit AA-100
I am having a heck of a time with this thing as it appears that
the 7591 tube sockets are wired inncorrectly.
As it is a home built job anything is possible.

Here you go
I have one of these too, but all the PCB boards in mine are fried and cracked with lifted traces. I am going to raid the outputs and power tranny and valves, and chuck the rest.
If you want any bits you are welcome to them.
Was quite ok sounding though. Make sure you replace the selenium bias rectifier.

Good on ya mate.
Thanks for the schematic.
I know what your saying. PCB's and tubes just don't seem to mix.
I'm glad that I am repairing this for a friend or I would be tempted to
make it a parts donor too.🙂
