Hello All, I noticed that the scan of the SC501 manual on TekWiki was almost complete but was lacking a little bit of information, particularly in the maintenance/calibration section (looks like some

I agree. I used the same topology (layer winding with retrace) on my 453. Although it's no good for volume production, it's low-tech and accessible to the novice. See topic and photo album titled "453

Ulf, Rewinding such a transformer is not for the faint of heart, the nervous or the impatient person. I appreciate your ability to do this successfully. -- Michael Lynch Dardanelle, AR

Great information Chuck! Most of us sometimes forget that our RMS meters do this! Thank you!

I got a .PDF of the winding specification and uploaded it to KO4BB manual sitebut I think that it may have ended up not in the \576-folder but in the rootsomewhere. I rewinded mine successfully after

Hi Stan, In an effort to keep my stock of electrolytic capacitors reasonable, I substitute the following in the 2465 power supply: ORIGINAL ---> MY SUBSTITUTION

OK I found many references to making new ones long ago. It does not sound practical. Does anyone have a black one for sale? [email protected]> wrote:

Peter, Yes, the Tek drawing is on the KO4bb.com site under in the Tek 576 section. I don't know know if anyone has rewound these, but a few years ago someone had a few new transformers made, albeit

Stan, 270uF caps work fine, I have installed literally hundreds of them in these scopes. Are you going to replace all the electrolytic caps, including the small non-polar parts? They have past it as

All seems to be well now. I found a high ESR 100uF cap on the A3 board in the -8v circuit (C1102). I ordered a bunch of 100uF/25V 105C caps and replaced all of them on both the A3 and the A2A1 boards.

Has anyone re-wound the HV transformer in the Tek 576 Curve Tracer? Is there a link to show the number of turns on the windings?

Leave it alone. It does no harm like this. Not a problem IMO.

Usually, the pins should be neither bent asymmetrically, nor straight (like they are in your other picture). The vertical deflection plate wires coming out of the CRT neck are very thin, soft, and

While I'm not an expert on the 2465B AT ALL, I wouldn't worry about the bends and I wouldn't "fix" them.? While they probably could take an adjustment to realign them, they might have already been

Hi again, I shot 4 better images: http://crypto-museum.org/TEK/2465B_CRTPIN.pdf first 2 suspect bernt pin uint, last 2 another normal unit. Really hope the veteran 2465Bers can comment! Bon journee,

Hello all: Here is a photo of the CRT VERT plate and term in a newly received 2465B. the area around the term is VERY delicate and affects Vert transient response. I have NEVER seen a CRT pin bent

Ok. Thanks all. Confirmed 485 sucks. In at back? Sent from kjo iPhone

Doesn’t that contradict post 1478-2b? Sent from kjo iPhone
