A truly tasty device! That's an excellent score. A great scope

Well, I have said device in my hands now and have been playing with it,
trying to see if all the bits work. I haven't played with the curve tracer
yet, but I have the manuals for all the plug-ins downloaded, also three or
four slightly different manuals for the scope itself. I'm having a lot of
fun working with it.
It plays pretty nice. I've been running through the checkout process in the
manual are so far there's only two concerns:
1. The display swims, more like twitches, from left to right, rapidly and
constantly, somewhat less than one minor division, meaning about half a
millimeter at a rough guess. It does it on any/all channels on both the
7A26 vertical amp and the 7A18 amp.
I don't have another timebase to check out, but when I switch to the curve
tracer instead of my 7B53A, the twitch in the on-screen readouts for
controls settings stops. Of course, with the curve tracer, you can't sync
up, but the readouts clue you that it is/is not dancing around.
I tried swapping the timebase into the A slot, instead of the B slot (the
7CT1N wants to be in an inside slot) but the twitch is still there.
2. The Ch1 input on my second vertical amp seems to attenuate the signal by
a tenth. The 4v calibrator at 1khz or DC reads 0.4v, set at 1v/div. The
other input on the same plug-in reads 4v. Set to 0.5 v/div, the bad input
reads about 1.2v. Switching the calibrator to 0.4v and the bad input to
.2v/div gives similar results.
I'm working my way through the manuals, learning as I go.

hey, since
the listing should be over by now (since you said you won
it)...perhaps you wouldn't mind sending us a link to the listing
so we can
all drool over exactly what you got? :P :D :)
Sure, absolutely. The item number originally posted for $299 has
been lost. The relist at my price is below. Try not to drool on the
knobs- they get slippery and hard to adjust ~(:-) that's me
with a feather in my cap.
