Wanted Tektronix 465/465 knobs

[dgta]

Need one or two volts/division knobs for a Tektronix Model 465 or 466 scope. Clear dial skirt reads from 5mv to 50V. Part number is 366-1426-00.

The numbers must be clearly visible and not worn out. I already have worn-out ones where you can't tell the difference between 1 and .1

Also if anyone knows where I can buy new I'd appreciate it.

Try a place called Sphere Research, in Canada.

They are out of those particular knob skirts, right now, but will get more. Email them.

Thanks gootee, I did see that. I also saw $29 apiece, which is a bit steep for a knob

Yeah, it seems pricey. But I didn't know how desperate you were. And the ones pictured look like new.

I'll see if I have any left, here. Might take a while.

You should definitely also ask in the TekScopes forum, at yahoogroups.com, and also in the sci.electronics.repair Usenet group, accessible through Google Groups .

On the other hand, if you still have intact plastic knob skirts and just the markings are bad, then maybe you could just re-do the markings yourself. One way, off the top of my head, would be to create the markings on a computer and then print them onto a transparent sheet, cut them out, and glue them onto the skirt. The transparent sheet could either be the kind for an overhead projector, or, peel-and-stick transparent label stock.

Cheers,

Thanks Tom. The knobs on my 466 are not broken, but the writing is worn and I have made a couple mistakes because of that.

I have thought of re-marking them myself but it would take a lot of time to get something printed that way. Additionally, I would have to first erase the existing (worn) markings. Either abrasive or solvent would have to be used and in both cases it would render the skirt non-transparent. I'm not prepared to spend several hours polishing it back to transparent

Given how cheap the 400 series Tek scopes are on the used market, I figured a lot of them get scrapped for parts and I just have to find a person doing that.

I might also see if I can hand-mark them with a sharp thin point paint marker. They don't have to be pretty, just readable and unambiguous.

Maybe something like this would work:

Some hobby and craft stores carry them or something similar.

Is this the input divider knob used for channel 1 and channel 2? If so, I have an extra 465 that I use for parts.

Gray5596, you have PM. Thanks for responding.
