Philco 38-2 Low Volume
#8

unless otherwise stated most parts have a 20 % tolerance. If both versions have the same tube count, I would consider changing the resistor to 40K IF the resistor was previously changed.

Did it ever work while you had it?

I will try to mark up the schematic as a picture is worth 1,000 words or 10,000 of my words.

Remember that low volume could be caused by alignment issues. If you do not have a signal generator, you can attempt to "peak" by ear but turn only a little bit and mark the original positions before "tweaking". As of now, there is no proof that that the issue is in the amp stages as opposed to the radio stages.
