Parasound HCA - 1500A Secondary Voltage values

Mindaugas · 20th February 2005, 04:54 PM

Does anybody knows concrete values?
There are three Bridge rectifiers. Two for amplifier power suplly.
And one for some protection circuitry.

Thanks in advance

Why dont u get yourself a voltmeter and measure them?????

Because there is no toroidal tranformer at all

.
I bought this amp from second hand shop. Price was : 150 $.

Thats why I need these values

Do u know the voltage rating of the large filtering caps??? The transfomer should be 1kVA and voltage more than 40V.But need to know the voltage fo the caps first.

Filter caps rated at 80 V. So I think voltage is lager then +-60V DC.
But concrete value is still unknown

So the maxmaxmaximum transformer voltage should be 56V.50V is possible to me
