RE: Dyna PAS2 preamp and amp impedance

Most tube amps from the 60's had high input impedances. The MC225 was 200,000 ohms and the PAS3x worked well with it.

A few SS power amps are up around 100k, also. Adcom GFA 535II for one. Dynaco ST120 for another. And the Phase Linear 700 into the Normal inputs. Lots more, I'm sure.
