Look over at tubes4hifi.com
they have a large number of parts and boards. Replace the obvious - electrolytic caps, clean the sockets, resolder all the joints, replace the power resistors with a beefier metal oxide.
Keep as much original as you can. However the driver board really is a soft spot on that unit. You can replace the 7199 with 6gh8 and an adaptor now. But the board really is past a usable date. Do get a replacement board.
The PAS - pretty much the same. Replace the power supply parts. Otherwise a good cleaning is all it needs.
And a fresh set of rectifier tubes isn't a bad idea.
but check the tubes4hifi sit. it seems to be down at this time but check back later.
