Those are Yamaha's own parts. They call them TVRs.
I'd be interested to know which model organ you found them in ?
I've only seen them in units built up to the mid 70's.
I've been looking for a source for some myself, so it would be good if they
used them in some of the cheaper lumps folks just want rid of, rather than
classic beasts ;)
