Hi gang,
OK, I have a R-4B with kind of distorted audio and you have to turn it
up almost max to get good listening level.
I don't have a spare tube (V7)
The resistance of PIN 1 to gnd is 150 ohm and the voltage is 7.6 VDC.
These are out of spec.
What do you think ? is it the tube, or ??
Just thought I would pick your brain before getting in deep.
I have a photo copyed book, but the schematic is pretty poor.
Either way I need to get GArey's CD (I have the C line one)
73,
Lee
