Philco 112 Cap Block Restoration, Part 3754
#1

I am attempting my first capacitor block restoration on a Philco 112, part 3754.  I found schematics and it appears the capacitors for the block are one 0.05uf, two 2.0uf, two 0.5uf, two 0.15uf and one 1.0uf.  It's a little hard to read the schematics. Can anyone confirm this and should the voltage for the caps be 630V to be on the safe side?
Thanks.

Here are the values from service bulletin #54:

   

I would use film caps for all of those (the ones I buy are typically rated at 630V).

There are discrepancies between the caps lists you two have given.
#4

Yes - there are. I'd go by the service bulletin, unless somebody else knows better.

If you can go e.me the number on the block I should be able to.look up the  caps.for you.
