Hi thanks for the replies! I've found a t948 new-old stock, with the original box! and sinece it is already in my country I really couldn't resist.. it should be here by the end of the week. I think

Unfortunately, I don't think you can gracefully remove the filter and really look at the CRT. Assuming that you have three color filters (the older TEK stuff used two), then what happens if you select

I'm just getting around to assembling my test module and at first assumed the -15V binding post was intended to be white and the meter connections red and black. But then I noticed the meter (-)

"...running the CRT outside the scope case." already did that twice, without any incident. As for caps in the PS, not now; that's simple, my current problem is much bigger (I had a job in the PS

"To get a white image you have three frames of the same illuminated image with all three filtered colors, and the human eye integrates the three colors together" in my answer to Siggi, I asked, why

Hi Martin, You can look at Tektronix parts cross-reference: https://www.sphere.bc.ca/download/tek_xref_free.zip It's on page 7-7. Looks like it's a dual "same package" but not matched as there is no

Awesome! Congratulations!!

Congrats, awesome job!

Hi all, I managed to shot one channel of my SC502 when repairing an old TV set. It seems the victim is a dual FET in the input differential amplifier with TEK part number 151-1031-00. To confirm its

Hi JP: Yes. Ozone is very reactive and corrosive. I think the idea of using "beeswax" is that... being a "wax" that melts at low temperatures... and perhaps having some properties that absorb ozone

I think that the way that the shutter works is to apply one of three filters (R/G/B) to the white CRT image. To get a white image you have three frames of the same illuminated image with all three

Hi greenboxmaven: The original Glyptal was just phthalic acid [phthalic anhydride] and glycerine [glycerol] both chemicals that are massively produced and used in world wide industry. Glyptal was one

I recently had a bad transformer in my 2235A. I posted a thread on the repair and a link to an album. I proved the transformer was bad by the simple to perform Ringing test... Pictures are in the

Hi Li: Yes. The OP about it spelled it "Gyptol" ... but, in the U.S., at least, it's brand named Glyptal. -- Roy Thistle

About 12 years ago I repaired a 2213A power supply and the main problem was T948. So basically yes, you are probably correct in your assumption that your T948 is bad as well, as it has happened

Hi, I got some questions on this, so I did a short writeup on it, and also the design files are available from there. https://diysquared.blogspot.com/2021/03/readout-for-5s14n.html Szabolcs Szabolcs

Today I'll re-read the manual, more attention to details "My guess is that the entire shutter switches R/G/B on successive frame refreshes, but I don't understand why the complicated shutter circuitry

Minor (moot) point: The 7B85 is a *delaying* time base: It generates the delay time for a 7B80 time base. Because the 7603 accepts only one time base (horizontally), a 7B80 would do the job just as
