Tektronix 565
jaseg brought a Tektronix 565 with a type 3A3 dual trace differential amplifier and a type 3T77 sampling sweep to the AfRA.
For years, people smoked right next to the poor thing. Hence it is filthy dirty, and additionally, it does not work. If I [jaseg] remember right, the vertical amplifier has some issues and the horizontal amplifier and/or the timebases are broken. Opening it and removing some of the worst dust, I discovered at least two loose leads in the sampling sweep unit.
My[jaseg] plans are to first disassemble easily accessible parts, reconnect broken solder joints, clean everything, especially the tubes, re-seat the tubes and finally try to get the device working.
