It's still got some funny stuff going on, but that's been since it was new - the original builder tried to correct those issues.

Have you replaced the caps?

I replaced everything in the device except for the transformer, meter, and panel switches.

Leaky paper capacitors and drifting carbon comp resistors make for a poor performer.

Here's the chassis before potentiometer replacement: https://pic8.co/sh/0J2blG.jpg

Here's what I started with: https://pic8.co/sh/XRXra9.jpg

The pots specified by Heathkit don't work in the circuit - the original builder changed some of the bands out for 5k as opposed to 200 ohm devices. Even that wasn't correctly correct, I need a 10k for one of the bands in order to dial it in properly.

Thank you. I'm waiting on one potentiometer to finish up.
