Mass replacement of all the other caps might seem like a good idea, but often is not. Far better to work on a process of elimination stage by stage. The OP transistors will usually be those 4 mounted to the heat skink at the rear of the chassis.

I know right? Caps, old ones even more, are always a good idea to replace.
For the transistors, if those usually are the ones then it's pretty much set that I have to replace at least 2 of them.

Thanks everyone, for the help. I'll come back when I've replaced those. Could be a while.

Cheers
