I see now. I was thinking when you said 10-15 volts you were saying positive 10-15 volts. I seem to always get signal grid and screen grid mixed up. Thank you.

I noticed in the riders schematic changes that R21 was changed from 500 ohms to 400 ohms to prevent variation of the 6A7 tube. My set had the 400 ohm resistor. I tried a third 6A7 and that solved my fading volume when set first turned on. So I guess the 500 ohm to 400 ohm didn't quite do the trick.

My filter choke was open so I replaced with a 200 ohm 5 watt resistor. I also changed e-cap (#59) from 6 mf to 16 mf to cut down on the hum. There is still some hum, but didn't think I should go any higher. Maybe I should get a new choke.

Those two circuit boards in this radio made working on this radio quite difficult. I think working on my 37-116 was easier.
