Dueling Heathkits

[Jon A.]

I checked the module, looks as if there's a part missing. Does the attached look familiar?

By the way, installing A/V jacks is a neat idea. Heathkits were made for hobbyists, so why not?

Those are the pins for the degaussing coil connection (on the bottom of the board). But that transistor looks like its cocked in its socket maybe not making connection.
I'd pull the board and check the solder connections.
