First off, hello all!!

Purchased a Maco 75 off ebay
Amp will not key up
Where to start?

Be patient, been around radio's a long time, have had a few tube amps and have been inside and know the dangers, just been awhile and need some reassuring. I know it's in the keying circuit, just don't remember where to start.

    Is it possible to be on a lake and have a homing directional beam being emitted from the shore so a person could navigate to that beam's source? For example at night to a jetty.
