That's it. I was going to bid on that black one, then had to do something else the day the auction ended and missed it. Then I picked up that yellow one instead.

Looking at your pictures I see why the volume control on my remote isn't working. Your set has that big stepper relay to control the volume and mine doesn't. This one was originally only meant to work with a one button remote. I have remote chassis 4H3, the two-button chassis is the 4G3, both schematics are in my sams folder. I've never seen the one-button Admiral remote, I wonder what it looks like?

I think the remotes that have "Sonar", rather than "Son-R", are newer.
