I also need to buy a 2430a carrying handle and face cover. This for a 2430a with Tekmate restoration. The carrying handle and face cover are needed for portability and completion. Kind

Hi Steve, Is there any reason you can't buy a 5V4G? There are 123 of them on eBay at the moment. Prices start at $12 for them and go up. I can test it for you to confirm its good if want to send it to

Considering the cost for a 5V, which IIRC is a rectifier with an indrectly heated cathode (*many* years ago).  You might want to take some silicon rectifiers and put them in, substituting for the

Many years ago I bought this from Deane Kidd. It has been in my back room since. The plugin is serial 000096. Serial 000098 sold for $100.00 as a parts unit. The power supply has no type number on

This may be blasphemy, but you could replace the rectifier tube with a couple of diodes. You may need a small resistance to adjust for the lower voltage drop in the diodes. 73, Dick, W1KSZ

Hi Michael, A bank account is definitely something we have to do. It is a little tricky because Michael is in Canada and I am in the US so we have to be sure we comply with the laws of both

Steve, I would strongly suspect a shorted filter cap in that supply. If you have an external variable B+ supply, bring the voltage up VERY SLOWLY at the tube cathode while monitoring the current.

Okay, it's a "valve" for our limey friends! Today I was able to do some more troubleshooting with my dad and my sons, on Dad's TEK514. I took along my thermal camera to help track down the short that

George, Do you or anyone else have a copy handy of "Winning with People; The first 40 years of Tektronix" to confirm this? I can’t seem to find my copy at the moment. Thanks, Greg

Hi Ragnar, Maybe Tek switched to these kinds of fans to make their instrument more energy efficient. With the heightened interest in being ecologically responsible many companies, like Tektronix for

Hello-- I'm offering FS one only Tektronix model 1140A load and current-shunt fixture That's in very good mechanical but unknown electrical condition and hence is offered as-is. The 1140A test

Hello Håkan, Thank you for the information.  I think this tells me what I want to know.   It is good to know that the hardware is all the same. I also have a TDS2024 but I don't have any plans

There have been a few times when Håkan looked up the cross references in the modification summaries, and the last 5 digits were not synced, e.g.: https://groups.io/g/TekScopes/message/60534 "In a

I'm pretty sure that's incorrect across serial numbers from different countries of manufacture, Chuck, but I'm happy to check and provide (dis)proof when I'm back in the lab... Unless unwelcome signs
