Default Problem with Sugden Optima amp

Hi all, I have a Sugden Optima 200 amp which I purchased in about 1996. It is solid state. It recently stopped powering up. Symptoms are: power light comes on but no audible click after about 5 sec and no sound output. Remote volume control still works. I suspect power supply is faulty. PSU is Antrim toroidal model 2998x part no 01849 428734. I can't find any specs for the PSU. All fuses have been checked for continuity and appear OK. Does my diagnosis sound correct? What causes the audible click in a solid state amp when the unit powers up. Is it a relay? Is this possibly the problem? Any advice greatly appreciated.

The relay could be a soft start relay or a speaker relay.

I would check for volts across the main smoothing capacitors as a first port of call.
