The Fine Things are Always Hand Made
What schematic best represents the BOL Philharmonic? The schematics I find seem to be for the pointer dial. How much difference is there?
Also, my BOL has had roughly half of the capacitor changed using mostly Solar brand. I presume this was done quite some time ago and was wondering how good these capacitor were/are. The radio works and is quite sensitive, but there are quite a few problems so I'm thinking of recaping the whole thing. I wish I had all of the originals so that I could restuff them!
I haven't seen any black film caps. Sal has black electrolytics. I only use name brand capacitors that actually have a datasheet. Nichicon or Panasonic for electrolytics, and I love the Panasonic ECQ series for film. But I agree, I hate seeing yellow capacitors under a chassis. They just stick out like a sore thumb.
As for restuffing, you need to pick your battles. As seen below, I chose to add a terminal strip and install new Nichicon capacitors underneath rather than restuff the electrolytics on top of the chassis. Why cut open one of the top capacitors and have a seam showing? I did restuff the 2 underside capacitors.
As for the 2 paper capacitors, I thought about just using some glue to hold them in place without being connected, but probably won't. This amp/PS is a far cry from the rust bucket it was, and I think I will leave well enough alone.
If you ever need some caps, I've been saving them for years and have (most likely) more than I will ever use. Let me know when you are restoring and what you need...

Any of the caps in this radio that were still original received the re-stuff treatment. I just isn't that hard to do. I dislike the looks of the Chinese yellow caps. However, when the originals are gone, one has to resort to Mike's strategy, as I have done also. But since there were so many and I wanted the radio working very soon, yellow it is! I don't have a huge inventory of old caps to re-stuff and the ones I do have say Zenith or Philco on them.
Mike, I don't think I have ever seen a "Scott" capacitor! I like it.
Thanks, Kent!!! I may need to do that on one of my next Scott projects. I'll let you know.
