Parasound HCA - 1500A Secondary Voltage values
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.:xeye:

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

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