The 47n value shaves a little low end off in comparison. Some of the tone stack caps look to have been replaced as well, but I ...

Which capacitors should I order for a 1978 OR-80?

I'm not sure what values of caps I should be ordering for it, though. Is there a list of all the caps that I should be replacing? H...
