Hello FRG-7 friends

I have purchased a relatively well preserved FRG-7 from a friend. I owned one as a young SWL and used it to learn CW by copying maritime CW broadcasts on HF.

I wonder if there are recommendations for a general restoration strategy. My FRG-7 is working quite well. I note the locking is perhaps a bit difficult to adjust in certain ranges.

?

I am aware of the need to check/replace electrolytic capacitors and I have also seen resistors losing their nominal resistance due to ageing effects.?

So, I am keen on any "must-do" restoration actions and also "don't do" ones. I can imagine that some fine-tuning may perhaps be necessary. Perhaps there are also some often encountered faults in these old receivers.

I bought my unit in 1977 if my memory is correct.?

I understand there is perhaps no separate service manual for the FRG-7. I recall seeing a "voltage chart" which may be the first thing to check.

?

Thanks in advance for any comments, advice and information.
