FS: Big ol' Tek O-Scope, NYC

[List, Christopher]

Well I had some focus problems with that used 2215A I picked up a couple
of month ago, but the helpful folks on sci.electronics.equipment told me
to replace (6) 510K resistors that tend to go bad in the focus circuit
and now it works like a charm! (sure enough, two if the resistors
measured 1.5M+

So now that I'm comfortable with it's reliability, I'm selling my old
one, and it's available to whomever wants to come to New York to pick it
up (it weighs about 50lbs).

It's a model 561B storage scope, with the following plug ins;
3B2 Horizontal Sweep - working but uncalibrated
3A3 Dual Differential Vertical Amplifier - only one trace currently
working, and needs calibration.
3L5 Spectrum Analyzer - makes wave shapes, but doesn't seem to be
working quite right.

I have the operation / service manuals for everything, and all the tube
driven sections work, so if you know your transistors you should be able
to get it in 100% shape. As it is, it works just fine as a single trace
scope, and the differential inputs are a really nice feature - though
calibration of the vertical amps would've been nice, I never got around
to it. It can also double as a space heater if you've got a cold dorm
room :).

I figure $50 for the whole package is a fair price.
