It was suggested to check WHY the heat occurs and to check the difference in input and output voltage. Is the heat unavoidable (class A energy waster?) or is it a design imperfection? Reread the thread. Understand. Now, RandomAudioGuy, next time don't do random stuff but mention brand/type as it is a bit wrong to want advice without giving enough information not to say it is irritating.
Jean-Paul, you've been very helpful and thank you very much.

I apologise for the frustrations caused to everyone. My initial questions were to confirm the voltage regulators and capacitors so they could be replaced. These questions have been answered and I'll be putting them in shortly.

While your suggestion of finding out the WHY is a great idea, I don't think I will be doing that. I had only intended to replace some of the components with new ones and people on here think I shouldn't even be doing that. So I think I'll put everything back and if it works, then great. If not, I'll wait till lockdown here is over and then find someone to have a look at it for me.

Again, thanks for yours and everyone else's help. I have no idea asking what types of voltage regulators and caps were would cause so much frustration for everyone.
