Philco 76 questions
#1

Hi. I am pretty new to the "part swapping" hobby and am looking for some suggestions. I won't be offended by the "dummy, step by step instruction or guidance." I may need that for some parts of this project Icon_smile
First, The radio has no volume output.
Tubes test in useable range (even tough that may not mean they are good, I understand)
Powered slowly with a variac, I also did not see any melting or burning components. Everything looks to be original or at minimum a repair from long ago, if any.
I realize caps will have to be replaced.
I will get to checking the speaker coil (haven't done that yet)

I haven't opened up the "B" filter condenser block yet.
I was wondering what exactly is in there? I mean I understand there are three 2.0 mf and one .15 mf caps in there. Is it a "tar filled" block?
Any suggestions on ways of mounting/fitting the new caps as well as suggestions on the types of caps others have used would be awesome info.

I am also wondering the values of capacitors part numbers 3897A and 3584B They would be caps 21 and 13 on the schematic.

I am pretty sure I understand the rest of what I am looking at Icon_smile
Thanks for any help.
Steve
