Всё красиво, аккуратно сделано! И вебсайт тоже!
Nice work!
 
i can't speak Russian or write in cyrillic like other, but your build is damn good !
I also have a look at your 176  :) how did this one cost in part at the end?

If I correctly understand your question
  - all devices cost on average $ 1,000.

yes you are(if it's the 176), tks for reply ;)
your schem and layout are nice, any chance you share the BOM? like with resistor W and sources for the nice tube angled holder

- Yes, and 176 also.

- Are you interested in BOM UA 176, or EQP-1A?

mostly the 176, but I think the community will appreciate both  :)

Hello, JBB,

  Sorry to bring back this dinosaur of a thread but, I'm using your schematics and layouts because you've done such a good job with them and I'm just wondering if you can share the BOM of your Pultec build with me.

  I haven't found C7/C8 and C9/C10 [which are each 50 uf + 50 uf 450V] but, I found some Mundorf ones that are 50uf + 50uf but rated for 500V. Could this work as a substitute in your circuit?

Here's a link:

http://www.partsconnexion.com/capacitor_ele_mundorf_hv500-r.html

Also, if you have any more of these beautiful pictures (besides the ones on your website), I'd love to take a look.


 
Hello, Coconuts,

A pretty good option is to use these capacitors Mundorf  50uf + 50uf 500V.
The more voltage to capacitors, the better.
My the photo shows that I myself use capacitors ARS 50uf + 50uf 500V.

Here are all my working photos: https://yadi.sk/d/FNmNefF13Fv2hC
