Resistors don't have " 1000 hour anticipated failure " bands !

I believe that they have a failure rating which is a percentage after 1000
hours, hence 1% per 1000 hours - 1% anticipated failure after 1000 hours. Is
this wrong?

Yes

If you don't know how to troubleshoot - give up or give it to someone who
does.

That's very helpful - I'll learn a lot like that - thanks.

Just being practical - it's not something that's easy unless you already know a
lot about repairs in general.

There's more scope for combustion with power amps !
