TTi CPX 200 Dual 35V PSU - schematic?

[John C]

On the off-chance, anyone got a schematic, or even service manual they could share?  My venerable old friend has developed a  fault - one half struggles to start up - all displays and LEDs flickering -  won't stay on (spikes when o/p switch hit).  Clears after a few seconds then clean happy o/p , but taking longer - so something deteriorating.  Schematic would be a big help.   Many thanks in advance!

The TTi CPX200 service manual is too big to post on the forum, but it can be downloaded from here:
