markc:
I have replaced C72, but this made no difference.
I have now found that the 15V supply comes from IC19 not IC16.
The supply to this IC is low at 12.4V.
Does anyone have a circuit for this set or at least the YSUS board?

daz:
change C37 + C78 as well but all 33mf caps in this area need to be checked with an esr meter
hope this helps

markc:
I have replaced 8 33uf capacitors around IC 17/19. The 15v rail now reads 13.9v or 14.6 v with the ZSUZ panel disconnected. Does this sound correct?
I have yet to replace the faulty ZSUS panel, but will not do that untill I am sure about this 15V supply.
