WTB (US) Quantity of small dia. Tek knobs for TDS3000, 5000, and 7000 scopes

Looking for a quantity of these, the more the merrier. Up to 20 or so, but any amount is good.

They look like this

Not at THAT price, though!
They were about $12 the last time I bought from Tek. Sphere is all out...

The TDS3000C is still a 'current product' and therefore you could purchase this knob direct from Tektronix.
There will be a minimum order value (which I guess is $50 or so?).
I don't know the cost per knob but it may be worth making the enquiry.
The eBay seller probably buys from Tek then adds his uplift. You just need to cut-out the middle man.

No, those are for a larger diameter shaft like DPO7K. The correct one is two pictures above that one. 366-0820-00

The TDS3000C uses a different knob. I think that Tek still sells the older knob, but they were $12 in 2017. I'm sure they are more now - every time I order parts from them, the prices keep going up. Same with Agilent.

Ohh ... coincidence my wife made a silicon mold these week-end to reproduce these knobs as i needed some.

But we need to make a new batch of epoxy resin to try it again as the epoxy ended being not sturdy enough (Critical fail of the mix).

If you can't find a source, once we've confirmed the new batch is good i can ask my wife if she can make some for you. But knowing her she'll ask some small $$$ for this

At the end it was just me being impatient. I got home tonight and the test knobs was fully cured.
Lots of bubbles for this quick and dirty moold testing but work like a charm !

[pmercier]

I wanted to have spare knobs that I can use with other potentiometer. I love their texture and feeling.
For these knobs I just didn't care of bubbles in epoxy and colour.
The news batch will have colors and less bubbles.

Thanks, but I already found some.

I think the price is cheap, if you need like this (3 CNY each one), I can help you to buy.
