Greetings everyone,

I’m hunting a pile of old ceramic doorknob caps for a rather large CW project I intend to build, as part of this season’s HV video series. If anyone has a box of them collecting dust in the back of your shop, I’d be sincerely happy to speak with you about giving them an entertaining new life.

They need to be 30 to 50kV rating, the larger the better. Standard screw mount, nothing particularly special other than they have to match.

I’m happy to answer any questions you may have.

Thank you!

With warmest regards,
cb

Have a look at the DK-1300-40. At $13 apiece in quantity, the price seems very reasonable. I clicked on the "quantity" button and it kept increasing so I assume they must have a large quantity on hand. This may be perfect for what you have in mind.

That's the plan B. But it's a much better case if I can find someone who has a dusty box sitting in the back of their shop. I'm low budget, and I'd much rather put some crufty old bits to good use while supplying someone with a good trade or even beer money, than just send a month's paycheck off to China.

If anyone is looking to trade, I do happen to have some mammoth capacitors (think 300lbs, 20kV or better, 10kJ, etc) that I'd be willing to consider for the right trade.
