[TR] [NET] Voltage Stabilizers

Dave:  I am sure someone on this list will have an original they can sell you.  After two failures, I sourced one from Marg Gruber in Alabama.

I see. Problem is, as you know, Bob, the "original" type is, for whatever reason, NLA.
So, solid state is all that's available. Those who have rebuilt their own voltage stabilizers
likely know the necessary diode number to solder-in to the circuit.  Until someone
develops a better idea/fix, we're forced to use whatever is available from the usual
sources, at about $20/a pop.

I was just looking for a reliable way, if possible, to test a solid state voltage stabilizer
that is not yet part of an instrument circuit....

Thanks!!

You can't really check them with a digital multimeter because the voltage on the original VS goes up and down so that it averages the proper amount, which should be something like 10 vdc. The modern ones use a solid state circuit to provide the voltage, not sure how you might "read" one of them. That said, am old fashioned multi meter (with an indicator needle) would probably work with the original-style VS. A test light would also be okay for testing, the inlet should be "brighter" because it's a higher voltage than the output... but a test light would be a good way to test, if you have a test light.

Hey all ~

Is it possible to test a voltage stabilizer to see if it's in good working order
if it is not mounted in a car, just a "loose" stabilizer? This would be either
the TRF 1488796 or Moss 133-555 (negative earth).

Thanks!

Dave
