Hello Thomas, Often a simple Google search for the part number brings you further, for instance 465(A) for the first transformer. A lot of info can be found at Tekwiki,

Has anyone had any success cloning the harddrive in the tds7104? I have tried a few options including a raw clone using clonezilla. I tell it specifically to clone the boot record. The disk image

Interesting...I did use my (3 year old) Variac last year to develop? a thermal sensor/display circuit for 3 phase bus-bars in electrical panel/switchgear. The circuit had to be low current, compact

Hello. I have come into some Tektrinix transformers new in box, and are wondering what they may be for. The parts no. is: 120-0800-01 120-0471-00 Also have some 154-0370-00 neon lamps, 148-0063-00

Hi satbeginner Thank you for good suggestion. I will find some suitable diode for cr907 and replace. By theime I am looking for a power supply to connect to the inverter. I will get back to you after

Hi to All, Based on personal experience (AFG5102) and that of two other acquintances (AFG5102, 2 x PG5110) I think the Output-Hybrid of these Modules isn't very reliable. I don't know for sure but I

Hello Saroj for now you do not need to bother about the line filter capacitors, if they ae not broken now, let them rest for now. Let's concentrate on the active power supply. This power supply is a

Hello Ernesto, I agree that most of us do not need the overvoltage. I did use it in final system testing of new equipment to ensure that it would operate properly at high line voltages. I think that

Hi Roy, Thank you for describing your useful warnings (diatribes). About the variac becoming a step-up transformer at the end of its range, this may not be necessary for us who have decent line

Hello Variac, variac, and variable auto transformer users, The first GR Variac I encountered was in about 1959. It was very old then. The brush is cylindrical, not rectangular like modern ones. I

Hi Ed, A stroboscope or LED Strobe like you made (great idea!) has so much in common with an oscilloscope that I knew I had to get a Strobotac after seeing how it brought repetitive mechanical motion

Hi satbeginner Thanks for the response I saw that document. But I do not have a suitable power supply right now. I will try that later when I get a suitable power supply. Tell me one thing how

Still waiting on my diodes, but I did go ahead and remove the bad diodes and attempt a power up with K600 removed. All seems to be well; I'm optimistic that once the new diodes are installed it should

Hi Ed, I viewed the pictures in the album and I'd be interested in seeing more about this. The GR units are certainly cool but if I could make my own for a few dollars, that'd probably satisfy my

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
