Re: Is $180(USD) a good offer for a Pfeiffer TCP 121 turbo controller?

Thank you for your replies,

It looks like there aren't any cables included with the controller. Are these cables usually easy to come by online/eBay for a fair price? Thanks.

Is $180(USD) a good offer for a Pfeiffer TCP 121 turbo controller?

I was recently offered $180USD (€152 EUR, $238 CAN, $251 AUD, £138 GBP) for a TCP turbo controller in working condition (shipping, handling, and other costs are included). Is this a good price, or should I be looking for something better? I'm not in a position where I can be throwing around my money...

Looking for a pfeiffer tph 330 controller

Hi all, A lot of you probably don't remember me, but a long time ago I built a pulse driver for a fusor. Things kinda came to a stand still due with the fusor due to some leaky valves that needed replacing. The whole pandemic has only put even more strain on my money supply, but I'm hoping to get of...

Re: Help Finding a Transformer Core Part

Greetings,

Thank you for getting back to be on the matter. It's truly an unfortunate incident, however I'm doing my best to make it right for the buyer.

The metal is about 0.014" thick, 1 5/16" wide, and 2 15/16" long. Thank you.

Sincerely,
Joshua Guertler

Help Finding a Transformer Core Part

Greetings, A few minutes ago I received the dreaded email from someone who bought my old x-ray transformer saying that he received it in shambles. By the looks of it, USPS gave it the old beat down, so much do that the actual box itself broke open during shipping. Fortunately, the core itself is pre...

Re: Neon sign transformer power: a new look

Greetings,

I recently got a 9 kV 30 mA NST with an internal resistance of 9.07k Ohms (not running). If I use a similar set up, what voltage output should I be expected, assuming that the current is roughly 20 mA? Thank you.

Sincerely,

Re: Neon sign transformer power: a new look

Greetings,

If I find an NST that is secondary midpoint grounded, would I be able to cut the ground on the secondary to make it operate in a way more desirable for this set up? Thank you.

Re: Neon sign transformer power: a new look

Greetings, Thank you very much for your advice and contribution, Mr. Feldman. Out of curiosity, would the following set up work safely? It's a slight modification to better fit my system, where the capacitor is connected to a grounded load. Thank you. https://docs.google.com/drawings/d/1UQy425Cb1DnX...
