I have a RCA TH-50A 1" field recorder deck which is a re-badged Sony BVH-500A deck. It was a portable 1" field recorder from the late 70's which did not have the color heterodyne boards installed for space and necessity in the field. B&W confidence playback only in the field with a few color flashes for fun.

It needed a TBC adaptor box to play color in the field or on-air and is connected to the blue connector in the photos attached...with credit to Labguy's website for the photos. The adaptor also supplied the DC to the deck.

I tried a 12v 75w 3/4" AC adaptor to push the deck but no joy. More amps needed.

Does anyone have one of these laying around for sale because you don't know what it is or it is taking up space in your shop? It is a Sony CA-500 number. Possibly a RCA THP-50 or RCA THP-500 number. No pic of the adaptor available.

I have a bunch of 80's 1" I wish to xfer and I don't want to go for the big studio versions.
