[TenTec] Argonaut 509 troubleshooting

[Jeff Imel]

I am the owner of Ten Tec Argonaut 509 Serial Number 00033.  It's an old
one.

It is not receiving right now and I want to do some troubleshooting and
bring her back to life.  Could someone point me to a publication that will
help me troubleshoot and repair her?  I am hoping to find something more
than just the schematics (which I have)...perhaps an actual troubleshooting
guide.

Thanks and 73.
