I have a CS-117 with a defunct transformer. The factory won't sell me
parts and the value of the unit will be exceeded by the repair costs.
Is there a way to estimate the value of the ac output (it looks like a
center - tapped output with 3 wires) so I can get this back on the
road?


Before throwing out the original , excavate under the covering and you may
find an o/c thermal fuse.

Connect a dual ps to the 2 main DC rails and slowly up the volts until
reliable operation and then add 20 percent or so and divide by 1.34 or
whatever for AC volts

Totally demolish the transformer, counting turns/ weighing /gauging the
wire, then using the formulae to discover the likely output V and I.
