Fairbanks-Morse model 8A FOUND!

[holmesuser01]

Was browsing at the Salvation Army today and they had me come to the back room and have a look at what they got today... an F-M 8A from around 1937! Its missing all the knobs, and someone has done a polyurethane restoration on the cabinet.

It's a console version, and I have already downloaded the Riders info for the schematic.

Currently, it is on my variac slowly being brought to life.

I checked the tubes, and found 5 of the 8 tubes to be very weak.

They are:

5Y3G rectifier
6K7G 1st IF
6K7G 3rd IF
6V6 output (metal--original was ST style)
6Q7G detector--cracked-- bet this is what made the thing die!

The 6G5 tuning eye is bright and green on my tester.

Others Good:

6L7G 2nd IF
6C5 (metal, had a G style at one time) Maybe this drives the 6G5 tuning eye?

The 6V6 output got replaced because the 'shorts' light on my tester flickers when I tap the tube. Id like to find G style tubes (ST) for this radio.

Believe it or not, I have spares of all of the bad tubes in this radio. This is what happens when you have been collecting radio parts, etc, for 35+ years!

All of the tubes are of different manufacturers. Anybody know what brands of tubes F-M used from the factory?

Also, since the knobs are all missing, anybody know offhand what style knobs would have been on this unit? All replies are greatly appreciated!
