Fully functional vacuum tube emission tester from 1947. The main capacitor has been changed to a modern replacement. Roll chart scrolls properly, and without any effort. Exterior case has some dings and scratches from 79 years of life, but the faceplate is in excellent, unblemished condition. Both latches and handle are intact and functional. Shown testing a new production JJ 12AX7 tube (not included). Includes Precision G-140 adapter for testing newer Compactrons, Nuvistors, and Novars. Also includes original manual, tube data, and schematic.

Cash pickup in Petaluma. Open to offers, as well as trades for broken musical equipment or other niche electronics (I am not usually interested in anything working). I buy broken synths! I fix broken synths! I also repair and re-grease KitchenAid stand mixers. Let me know if yours is dripping oil.

I also repair many other types of electronic equipment; stereos and electronic musical instruments, keyboards, guitar and bass amplifiers, effects pedals, and recording equipment, pinball machines, and jukeboxes. I do all types of circuit board-level component repair; new electrolytic capacitors, repair diagnosis, upgrades, and full electronic restoration of vintage electronics. Check out my work:
