Yes. I had a GK-500C many years ago, and it was very stable and output 
very nice AM and CW. I also had a 755-A VFO and used it with several 
rigs. It was very stable too.

The difference between the 755-non-A and the 755-A is that WRL moved all 
the tubes outside of the VFO tuning box in the "A" model, while there was 
at least one tube inside that box in the non-A model.

I have both a 755-A and a 755 now. The "A" model drifts a lot less than 
the non-A model.

I consider the WRL-755A to be about the very best VFO of that time 
period.

Both models include a separate buffer tube, which neither the Johnson 122 
nor the Heathkit VF-1 have.
