I powered the radio up on the variac. you have to turn the volume control to about 2/3 up to get audio. From there on up it goes to full volume.
If you turn it down below the upper third you lose all audio and have to turn it back up. I tested all tubes. ck. good. Checked vol. con trol. it calls for 30 ohms at full on and 50000 at volume all way down. I got 90ohms and 50000. there was a note that said some vol. controls will be higer than the 30ohms. It does change all resistance readings when going from low to high. This control is odd to me it is connected to the ant.on one side and simultaneously the grids of the rf tubes.
When I touch the 24 det. tube grid cap when on station it loses the station and you have to slightly move the tuning cap. to get the signal back.
I checked some of the resistors all are with in 25% or closer.
This will be a challenge to change the caps in. The tar cans are rivoted to the chassis. Any ideas on what I should start with as far as replacing or checking? Thanks for any help.[Image: http://i1336.photobucket.com/albums/o654...25665a.jpg]
