Hi all,
I spent some time today checking components and cleaning my 90 chassis. I am preparing to begin the restoration of this chassis. Here are some pics.

You always have to light the tubes once before resto, lol!

And finally, the best part. Notice the added paper condenser block on chassis right side. The date on the top of it says 10-10-36! It looks like that was the last time this chassis was serviced.

Other than the one added filter condenser, the chassis looks to be original and all there. Well the good news is that the transformer checks OK and powers up fine. All the resistors are within 20%, except for the two 490k's, which will need to be replaced. All the coils, RF, Detector, Oscillator and IF's at least have continuity. So I think a recap may be enough to get this radio to play. We shall see.
Now if I can just find a speaker, cabinet, escutcheon, and a few sundry items, lol!
By the way, no comments are necessary on the death cord used to power up the chassis for these pics, lol! At least it was fused at 1 amp and connected to my Sencore PR 57 isolated variac.
