Philco Model 37-38B Questions
#4

Richard & Morzh -
Great Information! Thanks Guys!
Yes that lug on the Volume pot IS connected internally to A+. I saw the glob of solder on the lug and "assumed" that it used to have a connection to it.
I also looked again at the Cap on the CT of the Volume pot. It must have been replaced at sometime way in the past. It has a Solar Brand cap and all the others are Philco Brand. Probably just picked one that seemed to work, in the past. I will replace it with the original value.
And finally, yes the added length of the outer windings would certainly add to the resistance! I thought it might be something much more technical. Keep It Simple!

Thanks
John N3MUN
