Thank you -I obviously had an early download. This versn is much more helpful, especially as it shows how to put the bits back together (all those screws !!) Thanks again. Tim [email protected]>

I guess a simple explanation would be that the higher the accelerating voltage is, the faster the electrons go from the gun to the screen, and spend less time passing the deflection plates, therefore

Ron, Well I have used my GQ4x4 for many years and it works fine for me. But you shouldn't have to keep heating your solder joints if you had quick solder flow on each pin. Seems strange that the

I remember frying some diodes during lunch on a brand new 575 in a class. Teacher walked by and said what are you doing? I and classmate said burning up some diodes. Good, good, he said, knowing we

Not sure what you mean regarding the accessory boards/widgets. This is the exact package I bought: https://amzn.to/3DBlYq9 I bought the one with the extras since I wanted them for other things in the

Well... Not a cleaning problem. Actually a broken actuator inside the "CH1V" switch section, it was the internal actuator position that was unreliable, not intermittent contacts. So, it will be

Hi Sigur?ur, Yes, but according to the manual,should have a different designation, not "A/B TRIG" but "A/B MENU", also B TRIG options seems different. It is almost impossible to tell if there is a

Hi again. To finish off this thread. For whatever reason, the 'spare' CRT damaged the video board, revealing that the CRT is dead and may well have been why the 2nd 492 had been stripped down

Craig, no joy with the EXER 03 sequence, tried it a couple times. Same error - 04 Fail. I did notice when I clear by pressing A/B TRIG, I get 4 CRT lines and gibberish on the bottom of the

May not be related but I had a lot of trouble with the GQ-4x4 and my 2467B when replacing the Dallas chip. I went with the GQ since I watched a YouTube vid where someone used one successfully with a

Ron, Try this exercise to see if this clears up your issue. Its a specific button push in the correct sequence. CYCLE ERROR CLEAR (Exerciser 03). This routine provides a way for the operator to

Hi, The manual doesn't look like the "interim" one: https://w140.com/tekwiki/images/8/81/070-1733-00.pdf They've updated the pdf file I guess. I also have the pdf from Artek, it looks

I bought a no error codes on startup S/N B057443. Inspection of A5 showed no leaking of the SMD eCaps, but the Dallas DS1225Y was 1991 vintage by date code. I bought a new Dallas DS1225AB-200+ from

It’s the effect of internal capacitance in the device and/or heating/cooling of the semiconductor junction.

Dave: I will make another round of them. April 5th is not far off but it's possible they could be ready for purchase then. -Thomas

Thomas! I will be visiting the museum on April 5th!!! Is there any chance you can save me one?!?!? - Dave KQ4VBE

Thanks Alex, 1) could you please confirm that your 2465B has a low serial? If so you should have performed the battery mod, else it should fail the battery voltage check, right? I saw that the

Hi, Can anyone explain why my Tektronix shows double curves in each step when I testing transistors? thank you! /g/TekScopes/album?id=301335

Perfect. I sent you my SN info directly, hope it helps.
