In the recent thread about variacs, there was a tangent off to strobe lights. Barry wrote: "Coincidentally, I've been looking at getting one of those over the last few days. Unfortunate what the bulbs

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

Hi Tom, I picked off the horizontal and vertical deflection signals in the 577. When the beam is centered (in either axis) the voltage difference between the deflection plates is essentially 0V for

Mine is in storage but I think that it is a 3RP1. Leon Robinson ?? K5JLR Political Correctness is a Political Disease. Politicians and Diapers should be changed often and for the same reasons.

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 and

That patent has expired, but in any case I doubt that anyone is manufacturing variable autotransformers with tracks prepared as described in that patent. Certainly ISE is not ISE devices are Variacs

I've been there before. Only an hour, Dennis? :-) -ls--

Hi Dale, Thank you for confirming that the cheap Chinese variacs (oops... variable autotransformers) are suited for everybody, everywhere, except... ... except for those who use and have been using

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

Where people are being encouraged to put their knowledge into Wikipedia, a lot. (Regurgitating outdated prejudices, not so much.) Grü?e, Carsten PS.: I’ve been teaching for a few decades now, and

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 due

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

Years ago I had a 511A that had a blue trace with a long green afterglow. It was almost like having a memory scope!
