I have just acquired an RCA AR 812 and have intentions of restoring it. However, how do you test the UV 199 tubes? I don't have a tube tester that goes back that far!!!

Hi Lou

Best just to test filaments. On UV99's they are diagonal from each other. Most UV99's will be weak anyway but ahould be usable if the filament is good.

Lou,

You also need to test the dreaded Radiola 'catacomb', the bees wax filled component case below the tube sockets. See:

http://www.geocities.com/tysye/radiola2.html

I also have one of these sets and tested the catabomb using a 1920's RCA Redbook continuity procedure..mine tests good! RCA used the catacomb sealed with RCA tamper seals, filled with bees wax and published very little info until later in the 1920s. Probably to keep the superheterodyne schematic/info as secret as this scheme could. My RCA redbook spans from 1923-1928 and has a lot of service information in it for the AR-812 and other early catacomb superhets.

Hi Lou

You can find some information under Radiola 25 & Radiola 28 in Rider.

Like Brian mentioned it isn't the best. Your radio will operate but don't expect very much.

Thanks - I suppose these radios are similar.

I do not expect much, having listened to a Radiola 33 every night at my home. Works well but not exactly high fidelity or selective.

But just imagine the folks that turned that brand new model 33 on for the first time back in 27, I'm sure they were in total amazement with their new light socket radio!

Make sure that you click on the pictures way down at the bottom of this webpage, there huge photos of the GE assembly plant for building the Radiola AR-812, the sets and technicians are great.

Want so see something very cool? At the bottom of this webpage, down past the referances are two huge photographs of the GE factory assembling and testing RCA Radiola AR-812 units! Very nice, you can look closely at the technicians, equipment and stuff on the floor and of course, the RCA AR-812!!!!!
