Carsten,
I think this is excellent advice, and I will also do all I can to encourage my employees and others to do the same, as will I personally.
Thanks,
Kyle

Political Correctness is a Political Disease.
Politicians and Diapers should be changed

Re: Tek 576 Curve tracer XY out
Dennis,
Could you use a pair of 7A22 Differential amps instead of the 7A13? Or a single 7A13 for X and single 7A22 for Y?
I know for sure that I have a pair of working 7A22s or at least one 7A13

Just added a big pile of 11K and 465M spares to stuff day...
Lots more hard to find spares uploaded to the stuff season page for you to browse through. Even P6134C 400MHz 11K Tek probes. Complete Vertical and Horizontal 465M plug ins (checked), and a huge pile

Re: sw503
Hi I have one working unit with option 1 (75 ohm)
When I got the unit, the frequency adjustment was broken. I fixed it by replacing a shorted electrolytic cap with ceramic one.
The case was bent

Re: Tek 576 Curve tracer XY out
Hi Thomas,
I added XY outputs to my 577 one day out of necessity when the HV transformer failed so the CRT was dark. Walther Shawlee was the one who suggested this as a temporary way I could continue

The SW503 seems scarce. Does anyone have a working unit which they might part with for a modest price?
If this is a goofy request, let me know why.
