Subject: [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...

If its in series with the transformer primary its R-43
330 ohms Charred is a bad sign. 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. While you can use individual
units you can get an exact replacement from
