Hello
surely there is some short circuit inside you amp, which causes heavy current flow, when you switch On it now. The main cause of this type of fault is with shorted audio output section inside the printed circuit baord. will have any shorted Integrated circuit [IC] or power transistor or MOSFET.
Your amp need service. Never switch in ON, until the fault has been rectified, as it may cause more component to be get damged.
Get it serviced by any expereienced service technician, as this work is skilled one, must have thorough knoledge in electronics, all tools to do the work, ability to loacate the faulty component etc. If you have all these, inform me. I'm happy to assist you further. The more you need is patience and concentration. OK.

It is capable of detecting cooling fan failure so I would presume it hasn't decided to engage the fans yet.

check speaker connections,make sure theyre not shorted any where

Hi...

There may be some internal fuses on that unit.

You can open it by taking the cover off and looking for fuses and discolored parts.

It may have a thermal fuse on the power transformer which then will require service

Check the web for service people in the UK

It might be any of the power supply Electrolytic Capacitors, check them out.

Individual (1 and 2) audio power amp sections bad.

You will need AC to AC converter that will accomodate US to UK mains. Look for power requirements of your amp on name plate and match with available converters online. Make sure power line frequencies match in/out requiremnts
