Only if its an old LINEAR supply as SMPS designs mostly
will not dot it.
I'm not sure what you mean by that....
The S100 power supply is terminally simple. Three
transformers
{8,16, 16 V AC}, three bridge rectifiers and three caps... thats all
folks.
Yup, I know ... Try finding a new, "available from a distributor"
transformer these days that will handle these voltages and currents, and I
will quietly slink off... That's the reason I'm looking for alternatives. I
can't find a transformer that will give me the voltages and currents I need.
Links to these distributors are welcomed...
