what auction. i get directed to ebays front page. is it US ebay?
ReplyDeleteI tried a search and didn't find it. The URL that was given looks peculiar -- Ebay doesn't usually expose the names of their individual servers in a URL like that. So I'm not sure where this URL came from. Was the auction taken down for some reason? Can't tell.
ReplyDeleteInteresting shot of the inside. I've never seen the guts of a VCS3 before. It's funny how different PCB design was back in the days before CAD systems and DIP-packaged ICs. I wonder what those metal-can ICs at the top of the left board are. I always thought the VCS3 was all-discrete.
The metal can ic are probably ua726 (paired transistors,with build-in oven,its used in the exponential generator to let track the vco's by keyboard cv in a desired scale)

A nixie frequency counter would have been hot.
ReplyDeleteI got a bunch of nixie tubes. Anyone know how to make them run? I bought a bunch of drivers from russia, but almost all were bad and I got depressed and put the nixies in the attic.
I have about 120 nixies of various types, pulled from old IBM mainframes.
Anyone wanna do something with them?
The metal cans on the left board are power transistors that regulate voltage, its a part of the PSU. The metal can on the middle board is the original ring modulator circuit TAB101 "Gilbert cell" IC. The three chips on the left board is the amps for output A and B and to the reverb. They were PA234 on the MkI
ReplyDeleteHi, i would like to know if someone knows how run a TAB101 ring modulator with the schematic gives by the datasheet, or maybe another circuit but with that IC (tab101). Please any idea??
