I purchased a model 66 that someone was restoring and the volume control is missing. The chassis calls for a Philco # 33-5006, 350K, audio taper, with switch. Unfortunately, I can not locate a replacement control. However I do have a Philco 250K, audio taper, with switch that I can use. In the past I have replaced volume controls with pots with a slightly higher or lower value, but never replaced one that is 100K lower than it should be. I know it will work, but am questioning if there might be problems down the road.

Also I noted that all of the schematics I have checked, the connection that should be there to feed B+ to the 1st AF is not shown. I know where to make the connection to fix this, but has anyone else ever noticed this?

I am encountering these issues because as I said, someone had been working on this chassis and left it an incomplete mess.

Thanks guys.
