[TR] [NET] Voltage Stabilizers

[David Friedlander]

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!!
