Last weekend, when I was in California to attend the event at the Computer History Museum, I also hit two of Jim's favorite surplus stores.
I started at HSC Electronic Supply in Santa Clara.
They had a selection of Tektronix 7000-series plug-ins (always good to see!), but nothing that I really needed (they were mostly slow time bases and a few low-bandwidth vertical amplifiers).
After striking out at HSC, I headed to WeirdStuff.
In the very back, they had a Tektronix 7904 for $250. No thank you.
The last time I was at WeirdStuff with Jim, we found an ancient custom-built rack mount ten-channel amplifier box on the floor near the back wall. Inside the chassis, there were ten Philbrick K2-X op amps and ten K2-P chopper stages. We bought it, took it back to LTC, and stripped all the parts out of it.
That was a good day.
