hello, do you think that I wired incorrectly double the transformer secondary? ok tomorrow I double check everything. thanks ...
I disconnected the power supply from ... PCB ... I measured the voltage on the capacitors directly, + 74 and -84, 😕😕it is strange, even on the other power measurement + 73 - 84?? you think it is a problem of the capacitors? ..... I do not understand😕😕
what is the reading when psu is unloaded? just caps...
that is indeed strange reading, it could be the circuit making that effect,
so isolate the amp for the meantime and check with just the caps on the psu...
these measurements on the capacitors are ... ... ... disconnected from the PCB.
I also tried measures, disconnecting the SOFTSTARTER ... nothing to do ...
I reconnected everything again, I measure the voltage again, just turned on the voltage is +75 v - 73, after a few minutes I find I measure is + 100v - 55v .... I do not understand
OK, then it's safe to carry on with power applied.
Draw a sketch of your transformer tappings and the way you have wired up the PSU.
Add on the voltages you have measured.
Post the pic.

can you draw a scheme how you wired up your psu?
amp modules are disconnected as you measured those voltages?
this is the wiring on the toroidal....
, The Project .... I got TNT, as in the picture I put two capacitors 22000uF + filters the input voltage of the toroidal and exit as well as provides TNT .....
can you confirm reading 56 volts on the red and orange leads taken off the
black and yellow leads connected together?
and can you also confirm that you can read 112 volts between the
red and orange leads? still with the black and yellow leads together...
sometimes color coding of traffos get screwed,
best to make sure you got your phasing correct..

here I am ....., combined yellow and black on red and orange I read 114V, red only read 56.5 V, 56.5 V only orange I read ... so it seems correct ... right? .... I checked the voltage on the + Vcc and-Vcc, all connected normally, starts ok +76 - 75, after a few minutes it is already +85 and -65, + 105 and get up - 55 ....
