Thanks for the recommendation guys. I can do all that, and they are right about the through hole recaps. Its not typically needed but only way to know is to remove a few random caps to test the capacitance. Cant do it in circuit. Shoot me a message and id be glad to give you a quote. Can even do it all ovee time if you like.
As far as why they dont need it is basicly they were top quality at the time, smd was newer stuff and well sucked at rhe time. All machines vuilt back then with smd need recaps now.
