I can't win with transformers! I took all or the RF transofromers out so that i could clean up the chassis. Measurements show that the 1st RF transformer (the one after the antenna transformer) has an open primary winding. it should still work, but just not on the distant setting. This coil is on the inside of the main tube so a bit more difficult to get out to rewind. I may leave it until I know that the radio works good.
I got all of the rust cleaned up from the mouse urine. took everything off and bead blasted it and painted. It seems a shame to have to do that, but i guess you have to protect bare metal after rust removal. It seems the plating is different on the AK than the Philco chassis. More like some sort of nickel rather than cadmium. Very thin plating that will peal off with light bead blasting. I don't know if that is an excepted procedure to use, but it did clean it up nicely and quickly, making a nice base for painting.
