I'm back, after some mindless 37-675 tasks.

I tested the tubes, and all but 3 are Philco, 2 of those are RCA M-R tubes: (6H6 and 6AD7G). The other is a Raytheon 6K8G, a sub for the 6A8G. There are 3 duds: 6N7, 6F6 and a 6Q7. This is the first radio, that I've had, with M-R tubes. I found that pretty cool, maybe it was repaired sometime during the War?

One M-R is a 6AD7G, in place of the 6F6G driver. Pins 1 and 6 are snipped, and I got confused? Icon_think

A well versed tech didn't have a 6F6 but knew what to do!

Mindless task number two was a quick vacuum of the top of the chassis and speaker. Hooked up a straw to the vacuum! 8) That got the loose stuff, but this chassis will need a good cleaning.

Time to bring out the DMM, and check for power transformer continuity. The 5X4 tested nearly new, so that's a good sign! Icon_biggrin

Edit: Power transformer checks out OK!

Still need to figure out a way to support this chassis, top side down. It'll be easier once the the tuner is removed.

I wonder if the original owners "decommissioned" this radio - when the tubes went south?
