    Yeah if it 120v only then no real chance of being incorrect voltage out of the transformer. Yes those KSC2690AYS's are great subs for the 2SC1318 and the KSA992's are the right ones for amp input pairs :thumbsup:. I wouldn't worry too much about matching the KSA992's having an adjustable offset circuit, also l have a bag of them here and they all test VERY close for hFE straight out of the bag, l was going through them all the other night just for curiosity.

    Yes it can be a therapeutic experience working on these old girls and it nice to have them running at their best.
