content: Looking for a quantity of these, the more the merrier. Up to 20 or so, but any amount is good.They look like thishttps://www.ebay.com/itm/272181727381?Not at THAT price, though!They were about $12 the last time I bought from Tek. Sphere is all out...

content: 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.

content: Quote from: pbarton on August 26, 2019, 07:57:58 pmThe 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.

content: 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

content: 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.
