Excellent, looking good.
Looking at the wirewound resistors top right, do you replace the original thick film soft start with wirewound?

No, the wirewound resistors are for the supply for the SG3525 (VAUX), had a few of these that were open circuit in a few older repairs of these amps. The ceramic ones for the soft-start can be replaced with a NTC but i am sure the 20R ones that are fitted are no longer available.

Ah yes ok. Don't think I've ever seen one fail which is why I didn't think of it.
Not tried to buy any of the thick film ceramic resistors for a while but then again I've been somewhat dormant in the Pulse repair business for the last couple of years.

The VAUX resistor/ zener circuit has blown a couple of times on some of the older generation C-Audio ones and these resistors were later updated on the XS series to 27K 2 Watt. Looking at Farnell, they do make the 20R value but are out of stock at present. Last time i tried to get them they said they were discontinued but that was a while ago.
