Gene and Geoff,
Could you guy do me a favour?
On this radio we have there is that resistor R2. That is, there are two of them.
One is in the 6k7 cathode ad is the feedback bypassed by the sensitivity switch, whichj shorts it when you listen to remote stations.
The other is on the tone control, on the sch shown right below the volume pot abd C12.
Now, the problem is with the first one. When I decided to check it, it was too low, about 1.4K. It needs to be 47K.
I do not see how the resistor can go that low. The sodering did not look like it was replaced. The colors faded so I cannot read the stripes.
The othery resistor is 47k' or very close, as it should be according to the BOM.
So I have my doubts about the manual, possibly listing a wrong value. I replaced it, but not sure about it.
Can you take a meter top it and check the value?
You do not need to desolder, it will read the actual resistance, just have the switch set on long distance and not on Local stations.
Thanks, Mike.
