[Drakelist] R4B Resistor Value
I picked my first B-line yesterday from it's original owner. Was very dusty but otherwise in fine condition. In checking out the R4B I found a charred resistor. I ordered Garey's B-line CD but haven't received it yet and this resistor was cooked and I couldn't get the resistance value. This resistor feeds DC to the red wire of the audio output transformer. The first color band is orange and the others are cooked black. BTW, I did not get any manuals or schematics with this equipment. If I can get a resistance value, I can replace this part. Everything else in there looks good. Any info appreciated... 73, Stew K3ND___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Looks from your description to be R43 which is 330 Ohms. 73 - have had my R4B/T4XB since 1971!

I suggest checking C-90D, the 100 uf decoupling capacitor which goes from the junction of this resistor and the transformer to ground. If its shorted it will take out the resistor. This is part of a 4 section can capacitor. If this section is shorted I would change the entire capacitor.
