Yamaha CS80

If you're lucky, it'll be the 151. Easier to get I would have thought.

Mine was the 152 - which I replaced, but would like another as a 'spare'... peace of mind etc... you know the feeling...;c)

By the way, your link don't seem to work.

Good luck and let us know what you find.
Cheers,
TOM
