VINTAGE TOSHIBA SR-50 OPTI TURNTABLE
Does it use a beam of light to read the groove or to read the signal off the stylus. Looks like its playing it with a led stuck to a golf ball. Can not say I have seen one before.

The size of the cartridge is that big because it serves as a heat sink for the build-in transistors. I read an interesting page with good info on vintage cartridges a couple of weeks ago but fail to find it ATM.
There is a datasheet somewhere too but in Japanese. That one is easy to find.

Actually, its not that big - the same size as a standard plug-in headshell. But it does get quite hot, since it has a 2V 300ma filament lamp inside it!
Big 'second-hand' problem is the stylus is non-replaceable - like a moving coil.
The turntable has a special pre-amp built in, because the optical cartridge doesn't interface at all with a conventional MM or MC or line lever input.
Someone gave me a new replacement cart for one of these, but until I create an amp for it, it remains silent. The specs look good though.
