I am sure that the C-audio ones were designed around the ST range (using T03 FET's instead of the plastic K1058, J162) but with a switch mode power supply which was built by another company (came into them ready made / tested).

Using the amps set to 4 ohm and bridged would be a bigger strain on the capacity of the output devices.  I am currently nurseing one of these beasts back to full health!


I thought there was only one PSU for the pair of amplifiers?
And in any case, separate PSUs don't preclude or favour bridge mode. It doesn't make any difference.

The PSU was probably the most interesting aspect of these amps. A series resonant design. Never seen another like it.
