Paper caps are paper caps, even the best eventually fail. I'd bring a set with original block caps up on a variac any day, but I would not make it a regular player till those caps are re-stuffed.
I just cited a statement what the old gent told me, not that I agreed with it.
The last Philco, I did, I restuffed the bakelite blocks.

I used a similar, but slightly different, pattern from Richmond Designs on my restoration. I ended up with a ton of leftover grill cloth as well, but I don't see that as a problem!



You'd be amazed by the sheer amount of repro parts out there for these radios. I was able to find repro tuner grommets for mine, as well as a new frame for the grill cloth and a knob for the tone control. I think you can even buy a whole cabinet if yours is too far gone...
I bought a rubber grommet assortment from H-F. A lot of them were the smaller sizes, that could be used for tuning condenser mounts.

Watching the youtube offerings... Feeling pretty confident the block caps will be a messy but fun experience..

Do any of the philco sites carry block by block capacitor replacement spec sheets?
I dont mind doing the messy work, but i definitely dont want to second guess about what exact cap and resistor i will be restuffing them with.. And i dont mind paying for the paperwork if necessary...

You may want to look for a copy of Ray Bintliff's book.

I collect Philco's and the book Jim mentions is a must have to work on these radios.

OK lookin for the book...

Does any of the parts websites sell custom rebuild kits for this or will it be a self made cap list like some of my last repairs?? Is there a bulk kit by justradios i can get that will cover the demand??

Most tube gear don't have model specific cap kits. Bob's capacitor does sell a generic $20 kit with 5-10 of each commonly used value in most radios.
If you do a good amount of tube repair you'll find it is cheaper and easier to go on Mouser, Allied, and or Digikey order up ~25-100 of each value of paper cap in 630V rating, a good assortment of lytics, store them in a small hardware organizing drawer case in a sorted manner and keep a stock.

I never have to take stock of the number of caps in a set (unless I'm quoting a customer a parts cost) or make a small order....Also most of the big parts houses cut you BIG discounts on bulk orders....Add to that the $10-30 fixed shipping cost is a smaller percent of the total order cost when you make a $1-200 bulk order (you could save $100 on shipping alone just by ordering 10 sets worth of caps at once instead of in 10 separate orders).
When you've worked on as many tube TVs+radios as I have you get a feel for what values go fast and what you can keep smaller stock of.

I can't seem to find the site I used to get the values for my caps, but this looks like it has the info. Be sure to click the "Next Subject" link at the bottom as well:

http://www.antiqueradios.com/philcorestorer/page9.html


For restuffing them, I used radial Wima (German made) caps. Some of the chocolate blocks have resistors in them too. They're just a piece of wire wrapped on a strip of paper and don't seem to go bad.

I was largely able to restuff the chocolate blocks without removing them from the circuit. I unsoldered the leads coming out of the chocolate block, unscrewed the screw holding it in place, heated it up, and pushed the guts out the back with a dental pick. In most cases I could pull the block far enough forward to completely push the guts out.

Restuffing is as simple as inserting the new cap in the back, guiding its leads through the holes in the top, and soldering them in place.
