I have the same outlook as Gary. I have bought & sold a number of
Tek scopes & have quite a good selection of test equipment to test
functionality & calibrate them. Anytime I put a scope I've fixed &
calibrated up on eBay, I stand behind it 100%. Some scopes I've sold
have had some problems that wasn't worth me monkeying around with it,
but I note the problems clearly and sell those scopes as-is or as
parts units. I, like Gary, am in it for the hobby aspect of fixing
up a non-working scope that someone can use. I cannot justify it as
a money making effort given the time I put into it. So I consider
the persons buying my scopes for a reasonable price as fortunate that
someone has taken the effort to fix, clean & calibrate them.
Of course, I cannot sell my items as being "in calibration" because
most of my test equipment is out of calibration. But I have certain
key test equipment in cal, a very accurate Fluke DMM, leveled sine
generator to 900 Mhz, etc., that I check my other equipment to. And
as far as horizontal timing, there are plenty of tricks I use to
check my frequency source, like using WVVB, and zero-beating local AM
stations for the higher frequency checks. While arguably not super
precise, it is good enough for scopes that are only accurate in the 1
to 3% range anyway.

Although there are many such vendors on eBay, the scopes I am
planning on
marketing will be fully tested and supplied with a manual and at
least 1
Tektronix probe. I have invested heavily in calibration equipment,
pulse &
function generators, etc. to insure functionality and proper
operation (and
because I like having lots of equipment). I have made whatever
repairs
necessary. I do this more as hobby than a profit center so I don't
count
the many hours some instruments require as part of the price. The
photos I
provide are not the grainy, out of focus, non-operating bogus
photos that
many post (and who knows what instrument they were photographing).
Mine are
guaranteed to be of the actual intrument with actual waveforms
displayed on
the instrument. This is a win win situation, I enjoy the
troubleshooting
and refurbishing and want to pass an instrument along that will
bring as
much joy and satisfaction as I have had getting it there.
