PSB Subsonic 6I
I have dead PSB Subsonic 6i with issues in SMPS. Is it possible to change only SMPS with any other SMPS? Do you have its schematics? any idea to repair the smps?
At first you should disconnect the power amp from the supplies to check whether it is the smps or a blown amp.
I had to repair some old harman kardon amp with quite similar smps - and I must say these pulse-width modulated veteran circuitry was a nightmare by design.
They blow up during power on and I had to design in some additional circuitry to prevent this from happening.
All in all, quite bad designed smps.
