Yeah and I have 2 very different schematics (at least at the PSU) for a Tek 422, both with the Tektronix name all over the pages and called 422, maybe 1 is a lab model or something, mine doesn't have an x-cap or choke, its just a fuse, and a thermal switch straight into the trans.
I have the right schematic, and the pictures match. However I'll wait till tomorrow when I get a small lightblub limiter, setup, the thing uses about 25W, and
I'll fire it up and very quickly check a few voltages off multiple secondary outputs.
