Screen Voltage on Canadain RCA 97K-1

Posted by Brian on 02/08/2010 07:32

Thank you Thomas. Given that I am using a digital meter and measuring 300 and 70 volts respectively, do you think this is reasonable compared to 275 and 95 as indicated on the schematic?

:...Sorry. You said Canadian 97K-1, which is not the schematic I looked at here (U.S. 97K). Hopefully the circuitry is similar. If not, though, the information I gave will help you calculate approximately what the voltages should be throughout the set. Draw a schematic of pure resistances, representing all tubes, resistors, and coils in the set, and break it down from the mass unit to all of the separate units. For resistors in series, you just add them. For resistances in parallel, it's 1/(1/R1+1/R2...).
