Ben, can you post a picture of the bottom of the chassis? There seems to be some confusion as to whether the radio has been recapped or not. Showing a picture of the components under the chassis will settle the question.
In the photos you have already posted, the caps visible have been all modern orange drop style replacements, so this confirms that at least some have the caps have been already changed.

I am a complete noob... I don't know what you are talking about.
EDIT: You need to go easy on the slang. I managed to figured out you meant "Electrolytic capacitor". There *ARE* three... unless I am sorely confused. There is a large yellow one, a grey one next to the yellow one and a smaller black and grey one to the upper left in the pic between two tubes base connectors.

It's installed in such a way that it's writing is facing the chassis body. However, I can just barely make it out. So yes, it has 3 capacitors.
They are 10, 12 and 22. They are higher than spec'd but as I understand things, that's generally ok. (Edit: or not...?) Having too small would be a problem.

Two possible issues:
1) We can't see for sure from the picture, but that yellow cap should have been disconnected if new ones were installed. Also, if only two of the three caps were replaced and one of the originals was kept (which appears to be the case), that one original section within the yellow multi-section cap is highly suspect and should be replaced.
2) Do you have any idea how long ago those 'new' electrolytics were installed? If you don't know the answer to that question with certainty, then you really should replace the 'new' ones as well. If an electrolytic has been sitting, unpowered for 10, or 20 years, or possibly even longer, then they are quite likely bad as well. I don't say this to cause you unneeded work or expense, it is just the reality of electrolytic caps.
Good luck.
Jon

The yellow cap is part of the restoration someone did. It's not a paper cap. They used 3 modern caps to take the place of the original metal casing multisection electrolytic cap. The three that were already pointed out.
I think you are seriously confused about what you are seeing in the photo. Why on earth are you referring to a Sprague TVA1706 as a "multisection" capacitor? It's not. I already provided a link to the technical information about it. You are also acting like it's an original, 73 year old capacitor.
Maybe some better photos will help clarify things for you. Please referred to attached photos.
On a separate note -- Over in my thread about the record player restoration thread, I discovered that the bakelite block cap has NOT been restored. It contains two small 0.01uF capacitors encased in tar. I will be digging out the old ones and putting in new ones.
