I was feeling smug about escaping my RCA rut today until I spied Dave's $50 621TS and broke into tears for some unknown reason. Still, for $40 and a 5-minute drive, I shouldn't gripe.
Also included: RA-103 service sheets and a box with about two dozen tubes. The cabinet has a loose, warped top, and some other boo-boos, but nothing I haven't dealt with before.
Check out the ginormous box cap strapped to the top of the HV cage. The "repairman" wired it in parallel with one of the p-s filters.

Something mysterious happened inside one of the 5U4G rectifers, but there are two more in the spares box.
Won't be trying this out any time soon. It's #4 in the project queue.
Anyone know the name of this cabinet? Oh, I need a complete set of knobs, too.
Later . . .
