[MRCA] In Search of TCZ Technical Documentation

[Nick England]

It turns out I have the TCZ-2 manual - it has a 115vdc dynamotor supply,
but perhaps will be useful. If anyone has the 115vac version manual, I'd be
happy to scan it too.
I have scanned and posted the 358 page TCZ-2 manual here:

Cheers,
