Hi all, I bought a For Parts or Repair 2465 PS on eBay. My idea was (and still is!) to make it work again so I would have a spare for one of my 246x scopes. It had parts missing, but in general it loo

I'm working my way through my PG506 (SN B031555), trying to restore full functionality before I try and calibrate it. I am working on the high amplitude mode right now, and have a few questions for th

I purchased a 492bp with some issues. One issue is that the SHIFT button have some intermittent contact making problems. Do someone have any idea how to fix this and knowing the part number from this

Can any one tell me what voltage you have seen with the "primary test load"? I have been working on a 2465B that had a burned smell on power on. (message 87960 and 87620) I think the primary problem w

For those with a 2465A (or maybe B) version; I just received a 2465. Very clean and good looking inside; probably heavy usage, though, considering the status of the blower: noisy. Another thing I noti

Hi All, I have managed to acquire new 2 x 1N3716 tunnel diodes some years back. I have never played with these exotic diodes before, but I do need to build a calibration fixture to align my 2465B hori

Hello. I've got a problem with a T935a scope. The indicator led on the front panel flashes, which indicates a faulty HV power supply. Thus nothing is displayed. As a disclaimer, I must say that I've w

Hi all, I've been trying to use use GPIB interface on my 2340A and had only limited success so far. I've bought a Prologix GPIB-USB adapter for the task. I can connect to the instrument and send comma

I just posted a nice assortment of FETs, including duals, Tek and HP parts, and J-series JFETs to the stuff page. I also added the amazing JPAD picoampere leakage diodes from Siliconix, which are idea

I recently acquired a 545A. It was quite a mess. I published some pictures of it on the OLD Tek Scope forum on Facebook. The Type D plugin was really a mess. I had to replace literally every small wir

Hi, I am faultfinding a 2445 that is not showing the calibration signal on channel 1. When I try to move the position on channel 1 this also does not move the trace. On channel 2 the calibration signa

While working on my 453, I notice that the LVPS board is isolated from the chassis with nylon covers on the mounting studs and nylon screws to hold the board in place to those studs. Since the various

I have a large number of 7000 series PIs (sorry no 7CT1N) and three mainframes which are taking space that I could usefully use for other stuff. All is in GWO and to specification. The mainframes are:

Can anyone explain why the 013-0099-02 FET adapter only has 5 pins on the back while the 013-0099-00 has 6 pins? Looking for instructions and cannot find them. I cannot make the right side of -02 work

So many people have been chasing hard to find FETs recently that I spent some time digging though all our semi inventory, and posted up the ones I thought might be useful for fixing test gear and RF i
