Sometimes you open a box and ... Surprise!

KAROB18 - 200-inch extension cable, factory-wired, 10-pin male screw-on connector to a threaded 10-pin female connector. It can be used to extend the distance between a Sony AVC-3400 video camera (vintage early 1970's) to the AV-3400 or -3600 or -3650 reel-to-reel tape deck.

56-inch factory-wired cable, 10-pin male screw-on to 8-pin male click-on, connecting a Sony AV series videotape recorder (the AV-3400, reel-to-reel, vintage early 1970's) to a monitor.




Notice there is also one of these cameras in this av-3400 outfit that we have. I suspect that this unit was near the end of the AV-3400 production.

Spaghetti City Video Manual
(click on cover to see a close up of this great cover art)

One of the most useful  books if you are still trying to use a inch machine. This book is historically interesting and has great cover and interior artwork.

 Even if you are not maintaining a inch machine this is  'one of those books' that will give you even more insight into the early video efforts. We, from time to time, have an extra copy at the museum... Contact us.  -Ed Sharpe archivist for SMECC


This is a brochure for the AV-3420CE that was the PAL unit version of the AV-3400

According to the folks that bought his storage locker and sold us the camera "discovered that he was a private eye, and quite the athlete with numerous esoteric interests including spying and scuba diving as well as under-cover work, martial arts etc., the military, knew a ton about electronics, etc etc etc."
