how's it goin reese,
I worked on it this morning, first of all the grid leak is rated 3 m-ohm. I got nothing when I used my dvm, but also have problems with that meter on anythng above 1 m-ohm.
Next went to the first audio tube, used a screwdriver, and got scratching out of the speaker. Next I checked voltages on the first and 2nd rf tubes (small dia pins) and got 91.4 v on each tube.
I then went to the first audio tube, checked the small dia pins for voltage, got 43.3 v and alot of noise out the speaker. Measured the 2nd and 3rd and got 85.2 and 82.8. When I got to the last one (detector) I got no volts. The transformer near the detector had no volts .The .002 mfd cap tested shorted, so replaced it with exact value orange dip. Then I checked the transformer and now I have voltage in and out of it. Also now checked the small dia pins on detector tube and got 124 volts. Tried the antenna lead thing and got what sounds like it's trying to tune in to stations, across all 3 stators. What I did take notice of, is there is some kind of wire wound shunt attached to one of the coils, and a clamp over it. I can see somebody was messing with it, it;s one of those things if you loosen the clamp, you can slide it to different posistions.
Also I'm running all 201a tubes in it. According to the manual, it should work satifactory with all 201a in all sockets. A special detector tube can be used in socket marked detector. Also if louder volume is needed you can use a wx112 or cx113 in the 3af socket. C power would have to be hooked up to this configuration.
What to try next?
