Put my Admiral 21K1 chassis on the bench last night for a few little "nits" that I was waiting on parts for. I had a 8.2 meg resistor to replace and wanted to test the one 3Kohm candohm chassis-mounted resistor. The candohm tested fine, so left that in. 8.2 meg replaced. Found one .01 uf flat molded paper cap (thought it was a mica at first), so replaced that too.
So the set has been totally recapped (except micas) and all resistors replaced that needed it. Then I remembered the two resistors in the HV cage. In the base of the 1B3 socket. So looked at the SAMS and here is what SHOULD be in there:
R89 - 2.7 ohm, 1/2 watt (HV Rectifier Filament)
R90 - 470k ohm, 1 watt (HV Filter)
Popped the socket open and could tell immediately that someone had already been in there at some point. Socket popped open way too easy and the solder joints had all been un-soldered and re-soldered. So the 2.7 ohm resistor tested over 6 ohms. Should replace that. Now for the uncertain part . . .
Instead of a 470k ohm resistor, there was a 150k ohm resistor in there.
Actually, had written on it "0.15 MEG, 1 WATT."
Does anyone know why this would be???? Now, I have the Admiral Tele-bar, which uses the 21L1 chassis. 21L1 uses the exact same SAMS and the TV chassis is almost identical to the 21K1 except for the plugs and circuitry for the combo phono/radio addition. So I brought that chassis out, popped open the 1B3 socket and whadda ya know???? That has the correct resistors in it. 2.7 ohm and 470k ohm. I see no service notes in the SAMS of any kind regarding this 470k ohm resistor indicating that it should be a different value. I also have the original service manual (which comes with a schematic) and that also indicates a 470k ohm resistor.
Any reason anyone can think of that I should NOT remove the 150k ohm resistor and replace it with a 470K one???
Thanks.
