Hello, I finally got brave enough to take the cans off the Expander Unit. Got the grid cap wires replaced and back together. I then began work on the RF unit. I took the unit out and replaced all resistors and paper caps. I left the mica caps in there. Doing all that required me to remove the three sections so I could get at the resistors and caps. I don't see how anyone can possibly replace the paper caps without doing so. As it stands right now the radio is play quite well since the initial power up just to see what I was up against. I spent about 30 hours on that RF unit. What a congested piece of work that is.

My B plus is about 300 volts vs 370 on the 127 ecap. Schematic shows 370 from B plus to B minus.  300 volts is what I had before I started the restore. I tried another 5U4 with same results. Any idea why 70 volts low?

I need to replace the filter choke (#120) as the one in the radio is a replacement measuring around 3K. Currently I am using a 400 ohm 5 watt resistor (maybe that is good enough?). Can some one tell me what Hammond choke I would need to buy? The picture with outlined in red is what should be in there. This is the link to the Hammond chokes. https://www.hammfg.com/electronics/trans...ke/153-159
