Jon, You might try emailing Forrest Burton (forrestburton@...). He produces replacements (3D printed) that seem pretty good quality.? I have a set of his replacements on my old Tek 454 that

I'll see what I can get for you.

David Rawding *used* to supply replacements for the 576 transformer, who I believe was once (and may still be) a member of the group? HtH David

Well found. Yes - I got mine from Mark Hennesy. It was in a cupboard at the BBC research department where he worked, and he saved it from getting thrown out into a skip. Craig

Nothing like as extreme as yours, but I had a 485 with a diffuse glow over about a quarter of the screen area on the right side. It varied with intensity control but not anything else until I noticed

The problem is that connecting up the voltage to the input capacitor will put a DC voltage transient up the innards of the AA501 while the cap charges up. That is the reason the 7A19 and 7A29 plugs in

Hello all: restoring a 2465B TEK scope that is missing the front and rear feet: 2 pcs foot bottom front plastic 348-0740-00 2 pcs foot cabinet cord wrap 348-0729-01 Also missing the special TORX - 15

I misread the parts list. The AA501 input caps are C1630/1, 1uF 5% 400V metallized film. The answer to my question turns out to be that the AA501 will survive it, but the Device Under Test may not ;-)

Thanks for remembering where the pics were stored! I used a pot core former, which was too high. So I cut a cheek off, shortened the tube and stuck the cheek back on (superglue). I used a cheap manual

How big is the original input cap? If it's reasonably small, you can put a much larger - say ten to a hundred times bigger - external plastic cap in series, with suitable voltage rating. A bipolar

Hi, Reg.Many moons ago I used an HP 54120 scope, similar to the Tek 11800 series.? Jitter crept in, and turned out to be the delay line was set for many nanoseconds.? When we finally set it back to

I know this may be a long shot but I am looking for an N connector and coax assembly for a 2712. Also if someone has a good condition plastic end panel for the back and the feet I'm looking for that

The input capacitor of the AA501 is rated at 50V. I have a need to measure a 4VRMS AC signal with a +33.5V DC offset (i.e. before the coupling capacitor of an AC coupled audio amplifier). I have no

I found a PDF of it here http://bee.mif.pg.gda.pl/ciasteczkowypotwor/Tek/sc504_cal.pdf, without all the deliberate obfuscation practiced by the site below. PDF is available at several other sites. EJP

My 11801 has developed a horizontal jitter. Does anyone have any info about what I'm likely to need to replace? Or any source of component level information about the horizontal section? I've got the

Tek fans, I've just switched on for the first time a 7104 that I picked up in a disposal auction recently. It came with the correct plugins (7A29, 7A29 with variable delay, 7B15 and 7B10) and the

Hi Colin, Great suggestion - I forgot his address was at the bottom of the page. Email Sent! Thank you and Best regards, Jason

Why not contact Kurt, the Admin of TekWiki and offer him the extra info? I'm sure he'd be glad to have it. His email address is on TekWiki at the bottom of the first page. Colin.
