Sound Technology Stereo Test Gear In For Repair

My friend Chris brought over a stack of Sound Technology gear that had seen very little use over the years. The ST1200A Stereo Tesst Panel  is the first piece of gear we tested and it seemed to function without issue but true test is after the other pieces are connected. Working on test gear is way more complicated than old tube amps...



The ST1700B Distortion Measurement System is not functioning. Chris found a handful of old electrolytics that need to be replaced I will be expert at the end of this one. There might be 40 caps to replace. Good experience for a solder monkey.




ST1500A Tape and Record Test System. Chris has all the tapes and records for these pieces. Very rare.. This is almost a computer has some early processors and eeproms. A very interesting piece. Getting these up and running will be interesting.

 Will post progress as it happens.

Jim Lansing - The Hartsfield

One of the most beautiful speakers ever designed. I haven't heard one of these but would love to compate both versions.

General Electric How Electronic Tubes Work - 1944

It doesn't get explained much better than this article from GE. If only I could understand interstage transformers as easily lol...
