Tek 466 oscilloscope

So I picked this up. It looked interesting, particularly for the option 5 which includes a tv H and V sync separator circuit to either sync to a whole frame or just a line of a video signal. (Which I could never get my 545 to do)

At first I thought it was dead, but the "horizontal display" switch was just dirty. And the CH 1 volts switch has a few positions that don't work. This thing is really compact, it looks like I'm going to have to start unscrewing some of the boards just to get in there enough to spray contact cleaner in the controls.

The ohmmeter works, but voltmeter reads low. I don't know if some resistors have drifted up in value, or there's an adjustment somewhere. There's no obvious-looking burned out resistors.

I haven't sorted out how to use the storage function yet. I think I have sorted out how to do the time and frequency measurements though. I really need read the manual, there's way more going on with this than my 545 that I'm used to.
