RE: Modifying/upgrading vs. restoration of vintage receiver

I have mixed feelings about this. Restoration (replacement of out of spec or aged parts with the closest new equivalent) is fine for things like power amps. However, many older pieces, both SS and tube had out of spec. RIAA equalization curves, tone controls that weren't flat at the center position of the controls, volume controls with serious imbalance, and balance controls that aren't balanced at the center position. In most cases, I'd fix those defects; even though those errors may have been what gave that piece of gear its unique character. It was very rare to find a 60's tube (or SS) phono circuit that had an accurate RIAA equalization, some were off by more than 2 dB. After 1972 or 73, things were a lot better, but exceptions still exist - maybe even deliberately by the manufacturer to give their gear a little differentiation.

As far as upgrading or improving circuit designs, I tend to limit that to power supply upgrades in rectifiers and caps.

And a minor rant here. I do not believe in changing the circuit topology in Dynaco tube amps.
