Guys
I have been given this amp as it has no power whatsoever so investigating this issue, there is no F100 Fuse in it so that won't help so I have ordered some T2AL 230v fuses (we are in the UK) but even despite that there is no voltage coming out of the power input (06SS1 on the board) measuring between live and earth on my multimeter..is this a common failure or perhaps the signs of rust around it and the transformer suggests bigger issues? any thoughts appreciated

Hello!
Is this the power supply you're talking about?

Check the secondary voltages of the mains transformer, then systematically measure the stages of the power supply, everything is clear based on the drawing.
Good luck with the repair.

Yes that’s the one, I have ordered new fuse T2 AL and power supply 06SS1 as there’s no power getting to that, checked the transformer using multimeter and all connections are showing continuity with very low resistance, just waiting for fuses and power input to arrive, tx for your post 👍
