PAS-3 preamp and Stereo 70 right? Very nice looking setup.
Yes and thanks! Found them on ebay 20+ yrs ago. Both were working. Both have been given considerable love. I can't believe the prices these things are selling for particularly the ST70. I think I paid 385 for the ST70 and about 100 for the PAS3.
I updated the ST70 with the Triode Electronics driver board and the SDS cap board. I added bias balance and cleaned up the wiring a little on the last love session. On the PAS3 I replaced all of the components, input selector switch, fabricated the input jack panel. I popped for the Dynaco branded Telefunken 12AX7s before they became so expensive. I paid about 100 for four of them 20 yrs ago. More recent upgrades are the SDS power supply board and replacing both circuit boards.
