1936 Philco 620F - PhilcoPhan1936 - 07-02-2017

Fellow Philco Phans
I'd appreciate some help.
I just picked up this 1936 620F, and it has been worked on. Most noticeably, the grill cloth . I plan to replace it, but the backing is a flimsy cardboard.  
Would anyone happen to have this or a similar model that would be so kind as to get a tracing or a good quality pic of the original grill board for me

Thanks in advance!

Not sure if this will help at all, as it's a model 625, which may or may not have the same backing board, but this reassembly video shows how it looks beginning at around the 6:40 mark:

One more Question: I'm in the process of recapping, and need to know the values of the tone control. Part No. 30-4316.

It's a bit clearer on this scan of service bulletin 218A:
https://drive.google.com/file/d/0B64cfWaiGjfKSFBLcF9UcVlNYzg/view?usp=sharing

0.02uF in the tone control for 61.

0.003uF tubular for 61a.


BTW - nice radio Jeff!

Thanks Nathan!
Hopefully this 620 will go smoother than my 1st!
Took me 13 months to get my 1st up and running.
So far it's going well.

I made this video a couple nights ago. It's up and running. I have a reproduction dial on order from Radio Daze, and a grill cloth from Richmond Designs . I'll wait until I get the dial in before doing the alignment, as the one on there now is incorrect.
