RCA Victor Canada SCH884 – looking for information

[Elektrishun]

Hello

I am a new member trying to gather some information about a recently acquired RCA Victor Radio and Phono Combination. The model number is SCH884 and the unit was made in Canada. Despite numerous search attempts I cannot find information on this radio. I haven’t attempted to power this unit up yet but I was told that it was working. Any information and opinions would be greatly appreciated. Thank-you!

A little background… I am a retired journeyman electrician with an interest in electronics new and old. Among my interests I like to build circuits for a variety of projects including an FM Transmitter, Capacitor meter, and a lab DC Power Supply.

Radiomuseum.org lists several rca units in the SHC series from shc-460 (1958) to shc765 (1963) if you go to the radiomuseum.org site and search by the exact tube lineup you may find a schematic that will help.
Good luck and welcome to the CVRS.

Les,

Appreciate the response. I have been to that site and a few others. I now have a schematic that might be close.

Thank-you

I have the electrical schematics for my radio. I am in the process of replacing the electrolytic capacitors. Nothing has been disconnected yet as I am waiting for parts. While I wait I have been mapping out the multi-connection capacitor. This capacitor’s specs are:

– Plessey
– 60-60-40-20uF
– 350V DC
– 425V Surge

In the schematics the capacitor is identified as “C45A @ 60uF, C45B @ 60uF, C45C @ 20uF, and C45D @ 20uF“. I am not certain of the pinout for this capacitor but obviously one of the connections is 40uF. Any thoughts as to why there is a discrepancy between the schematics and the actual capacitor? Until I am ready to measure each connection of the capacitor I know one connection will not match the schematics.

BTW – I found another schematic online that appears to be close to the one I ordered and the specs are the same for the multi-capacitor -> 60-60-20-20. I know the history of this unit. It was purchased brand new, was never repaired, all original. Multi capacitor is marked with “May 63” so another indicator that it is likely original.

With my capacitor order I missed this discrepancy somehow and ordered what I seen marked on the capacitor despite looking over the schematics, as well. I am using 4 individual capacitors to replace the original. I ordered 60uF @ 450V DC (x2), 40uF @ 450V (x1), and 20uF @ 500V DC (x1). Should I carry on and replace everything as I found it or order another 20uF capacitor and follow the schematics?

Any advice is appreciated.

Thank-you
