Thanks for a fast reply Harvey!

I'm not a professional, just a hobbyist and I love to fix anything I get my
When I see how people dump everything, before thinking to fix it, it makes
me sick how wasteful we become.
If I could fix stuff for free I would, that is how much I love to give
anything a second, third... chance to do its work.
Helping handicapped and old/poor people brings me more joy, when I see
their eyes sparkling again!
So not for now I don't need a perfect scope, but a working one that gets me
there. My plans are to teach anyone some basic electronics and encourage
them to have a hobby.....
For now the scope does something, that is much more than when I received
it, so now I like to play and learn, since my modern scope is nothing like
But I always wanted Tek scope so I have one and it needs a checkup and or a
way to make it work well.
I found on eBay *Tektronix PG506 - * but they are mostly a PLUG-IN style.
Can I run it without a housing?
When I look over the pictures for *Tektronix PG506 *it seems to me that the
power supply is in the base unit..... but I don't know anything about it.
I have skills and even 3D printer, so I can make something to cover the
back end, where I can make a power supply connect....
I'll keep your email and start looking for a complete *Tektronix PG506, *it
can be a great addition to my tools here.
Harvey, you are great help and the rest of the guys here are also very
helpful, I'm glad to belong to Tektronix group!
You make me smile more and more!

Does anyone have one and what should I look for in a used unit?good cosmetics, good reports on the seller, and an idea of what you'd
have to replace if things were bad.
Are they mostly good or is there some parts that make them less reliable?Ebay and local and you takes your chances....
Where do you buy your parts and who is reliable to buy from forTektronix?
Major distributors (Mouser, Digikey, Arrow, etc) for standard parts.
Sphere and Qservice are most reliable, buying another with a different
problem is often quite useful.
I do have Aktakom Function Signal Generator, 50MHz - 2 channels. Is thatFor waveforms, maybe. (linearity).
How do you measure the voltages, and the frequencies (vertical and

want to get.
Thank you guys, you have helped me a lot!wrote:

Most of mine worked. The digital circuitry, as I remember it, is
relatively simple. Just checked the listing. Looks clean from here.

Also...which plug ins are recommended to cal for building my golden
The typical plugins for a 7904 (and that's a good choice, IMHO) are
least one if not two 7A26, and a 7B92A (which I happen to like). If
you want the flexibility of two sweep plugins, the 7B80 and 7B85 will
do. If you have a 7103/4 and a 7B10 and 7B15, you could use them but
the sweep is not calibrated at the highest frequencies, but those
could be moved over to the 7103/4 when needed.
For things you'd want:
067-0587-01 signal standardizer. The 01 is intended for 500 mhz
scopes, the 00 is for lower bandwidth, and the 02 is for the 1GHz
bandwidth scopes. Needed to keep the mainframes all agreeing with
each other as well as provides some nice linearity and gain signals.
You could use the 00, but it wouldn't allow you to check out the
frequency response to the limit of the scope's bandwidth for higher
PG506/TG501 SG503/SG504 TM500 plugins that provide calibration
signals for vertical and timebase checking, as well as frequency
response. Those will do any scope. The signal standardizer is
specifically for 7000 series mainframes.
You could also go with a CG501 (TM500) or a CG5001 (TM5000) module
with the appropriate frame. Note that the CG series may need a
specific head to supply the right signals. Those heads may be
difficult to find.
My favorite (depending) setup in a 7904 is a 7A26 (or 7A24 if I need
more bandwidth and can tolerate a 50 ohm input plugin), a 7D12 with
M2 (sampling) module, a 7D15 counter, and a 7B92A sweep.
