Radio restoration questions

Post by Jtz622 »

Hello, I recently acquired a wonderful VE 9-16 radio/phonograph. I am in the process of restoring it, and I have a couple of questions.
First, does anyone have the schematic for this radio? It is not pasted inside the cabinet.
2. How do I go around replacing the capacitors? Do I have to replace the Condensor bank?
3. The capacitators have no markings on them. How can I replace these?
4. Will it be possible to get the electric phonograph working again, even though it is so old?
5. What else must I replace? Should I replace every box that doesn't give a reading on my circuit tester?
Thank you for any help.
Please explain in lay mans terms.

The Electrola 9-16 is not a good candidate for a first restoration. Whist the tuner chassis is quite simple, the AP-777 amplifier/socket power unit is rather complex, and unlike most later sets in both construction and circuitry. This amplifier operates with very high voltage on the plate of the type UX-250 output tube. It runs smack dab at the limits of its components, and is known for burning out power transformers. ]

You would be well advised to lay this set aside until you have accumulated a bit more experience, or to have the electronic work done by someone familiar with these late 1920's sets.

Here is the schematic:

Whilst I am spending most of my time in Cleveland caring for my elderly parents, I do frequently return to my home in Southern Michigan (Hillsdale County) and could arrange to get copies of the RCA Red Book service information and perhaps offer a hand.

Not questioning your capabilities but you really need to educate yourself in electronic circuits and components before attempting this repair. Start with some less complicated radios and work your way up to this one. I suggest that you start by going to the Antique Radio Forum and asking for advice there. Personally, I recommend that you have this one restored rather than trying it yourself.

I have restored a few simpler radios before, a 1924 Sonora battery console set, 1947 spartin set, and a 1939 philco.
Sorry if it sounded like I've never done anything before. But the thing that has. Me confused is the condensers and capacitators in this one. While some do test positive, others test negative. Also the schematic on radiomuseum i cannot see or down load. I don't want to pay $25 for it either.
Why did the manufacturer not label the capacitators or condensers?
Also, would it be wise to replace the condenser bank in the power unit?
I do believe just about everything is working fine in the power unit except a flat thin metal capacitator.
The tuner has more capacity tours that need replaced.
Thank you

I'm sorry for the assumption I made about your experience. Good luck with it. Do check out Antique Radio Forums, though. I think you'll find it very useful.
