  The PSU in my VAXmate failed recently and I think I
have found a
 problem
 with one of the windings on the transformer not ringing when I test
 it with
 a ringing tester. The technical description of the VAXmate says that
 one
 winding is operated in flyback mode and I wonder if that has any
 bearing on
 the ringing test. Also, one of the pins appears not to be connected
 to
 anything else, so possibly a broken (melted?) wire.
 Can anyone help with the following questions: 
The transformer is basically only intended to provide AC at a specific
voltage while preventing surges and noise from the utility to create
havoc.
What voltage is it specified to provide ? If so, can it be replaced
with maybe a new AC to AC device ?
