I am attempting to revive a Vax-11/750 that I recently acquired. During the several moves
of the machine, damage was done to the 875-A power controller. The fuse holder, power
control switch, and circuit breaker were all damaged.
In particular, the circuit breaker (CB1) had the handles snapped clean off. The
individual poles can be moved to the ON position, but always return to the OFF position.
I am looking for a replacement of either the entire power controller, or, just the circuit
I have located a for-profit source of an 875-A, but it will be a few hundred dollars to
If anyone has a spare 875-A or breaker, I would be extremely grateful.
