There are 2 stock faults on old PETs.

Firstly, the power harness connector (IIRC a 0.156" header) is rather 
under-ratted. It tends to oxidise, get even hot, oxidise some more, get 
hotter, etc. If the plastic has turned brown, replace it. Clean it anyway.

The second is that I've fixed several PETs by replacing the 
cheap-n-nasty IC sockets with turned-pin ones.

There used to be a lot of Commodore schematics (and other info) on 
ftp://ftp.funet.fi/ . I hope it's all still there or somebody has 
mirrored it. I don't know if your machine is specifically there, but you 
might find something close enough to help.
