The resistors in my radio all read high, I have soldered some turns of copper wire around a resistor to give the correct reading but will this result in a dry joint in time.

? . .? . .? The onliest-est resistors that I even see on a 55 that might be trimmed via copper wire "add ons" would be the low value 20 ohm units used for "derived center" acquisition on the sets filament supplies. |

From memory I think they were the 20 ohm resistors measuring 32 ohm. Set did improve.

I would ask the same question as Thomas...Wire wound resistors will be ok in your AK unless they are open. There are 2 carbon resistors in the power supply which will be high in value. They are under the power supply board on right side. The grid leak carbon resistor, looks like a fuse, will be open or high.

:...What resistors and how far off value? Did this affect the set's performance?
