MR-21 schematic needed

[Christopher John Galbraith]

Hi gang,

I'm new to this list, but have been a Heathkit fan my entire life.  My
first "real" radio was an HW-16/HG-10B combo around age 11, with many
other pieces to follow for years to come.

I have an MR-21 marine direction finder/receiver and could really use a
schematic.  On powering up, the audio goes out--and I discovered the
push-pull output PNPs get really warm.  I suspect a bad electrolytic
coupling-to-output capacitor; any suggestions here very welcome, too.

I've looked for the schematic at BAMA, etc. to no avail.

Thank you for any help, and happy new year.
