Wish All the DIY Shop stuff came as fast as the Fedexed cases from Italy. Full marks to those guys for great product and fast gloabal delivery. Khozomo stuff i have on order from Poland is moving pretty fast by UPS too. But the DHL stuff disappears into an electronic abyss for days. So much excitement with all the goodies coming.
Bommer for me .
I can't do the payment at Diyaudio store because I dont have Visa etc. only Paypal .

You might try contacting the store about that. I recall some previous
posts on this point and tjat Paypal fees may be higher for the store
than straight credit card transactions. They may still be able to
process your order with a paypal payment 'offline'.
instead nutube an ECC82 or 83 at 48V plate could achieve the same H2 profile with 8Vrms output?
Listen - reading make no change in sound. Electrolytics with a bit DC on sound ok. I would not use them when no dc. And not more then few volts.
I think reading the article can give a hint when to backup a listening experience with blind tests. It is easy to get fooled by the brain.
Personally I listen to a setup for a very long time (weeks or months) before I make a change. Then I know what I like and what I don't like. It is interesting what re-positioning of the speakers can do to the sound......much more than changing a quality cap with another quality cap.

Thanks for the tip .
Already done , this morning and received an answer and all sorted out .
16mm caps (Panasonic fm 2700uf/25v) barely fit and leave little room for resistors. Choose wisely here...it’s going to be a trade off of capacitance vs. quality. Typically I use silmics but a 16mm Silmic is only 1000uf.
I believe the silkscreen is 13mm.

Are you building both versions of the nutube? If you do I'd love to compare notes. I have built both versions myself.
Jeffrey.
I remember playing with electrolytes, 2 of them in a back-to-back configuration, with a middle point "biased" by a local +Vcc. That sounded very good.
Electrolite on its own, especially if it can't see any DC at either end, sounds lousy indeed.
Noob question... Is it bad practice on input wires to the Pot, to twist a single ground and both + channel input wires together in a run? Or do I need to run separate twisted -/+ pairs to each input RCA?
A new Korg B1 Nutube preamplifier is alive (and makes music ...) !
I must say that I am extremely satisfied with the result and especially the excellence of the sound ! (And I have absolutely no microphonic effect, but I do not listen to music at a high level ...)
Thank you once again to Mr. Nelson Pass for making public this achievement and 6L6 among others for his valuable advice throughout the many pages devoted to the realization of this project !
