B1 with Korg Triode

[Zen Mod]

I'm a big fan of Japanese people.
Maybe Hungarians and Japonese are close relatives.
One of my very favourites film maker is Akira Kurosawa.
As well one of my very favourite actor is Toshiro Mifune.
But I really can't understand, why they chosen 2mm for pin spacing for Korg Nutubes?

thickness of dozen Katana blades ?

At the middle of seventies, we have an Akira Kurosawa series on TV.
That was the time, when I read first The Sound and the Fury from Faulkner.
I must have to say, they are both, who definitely have to declare my point of views of life, until now, and then, while I live.

I built the first b1 a couple years ago. Just saw this new iteration being discussed. Aside from the pleasure of building it, is it blowing anyone away with eargasmatronic glory?

 

[Michi124]

Not really eargasmatronic glory, more of a Toshiro-Mifune-like presence.

I love clean power ... sigma11 (clone) from amb.org with active rectifier.

Nice, I read a little aboutthe sigma11 on AMB Laboratories and also found this build guide: McFrede.dk - Sigma11 Power Supply
What is the consensus about this type of power supplies?

 

[carsten.witt]

Thanks, but ... the power supply (TRIAD WSU240-0500-13 from Pa list) make ripple & noise around 200mV and this one has only 6µV .. so what should I say more?!

Hi Carsten,
Where did you find that version of Sigma11 psu?

Thanks,
Vunce

@Rewind,
nope! Please if you post some links, are shure that is what some one is showing! Vunce asked for "that"!

@Vunce,
a friend of mine made this.

Yes. It sounds nothing like the original B1. The NuTube is an incredible device and is very much worth trying.

Thanks Carsten
Have you used it yet with the spiffy AD chip?

Triad psu is perfect.
RCRC filter on B1Triode pcb do his work so noise numbers go much lower.
BTW use of two car 12 V batteries in series can be interesting

@Vunce,
please what did you mean with "spiffy AD chip?"?

@Soundhappy,
yes, but cleaner is nicer and not use car batteries ... this is another discussion worth in another thread. ;-)

@Vunce,
please what did you mean with "spiffy AD chip”.

“Spiffy”= cool, neat, new

AD = Analog Devices

 

[carsten.witt]

Ah, ok!
BTW, PM to my friend is on the way ....

 

[Vunce]

Sometimes, I forget how worldwide this forum is and localized “slang” uses of words are not interpreted the same.

 

[Soundhappy]

@Soundhappy,

WAF is important
Batteries from BMW car sound the best just a joke!
then filtered RCRC again for cleaner clean hahahahaha

Regarding the much talk about microphonic I watched these magnetic field feet at Jac Music:

★ J A C - M U S I C ★ EMISSION LABS TUBES ★ YAMAMOTO SOUNDCRAFT ★ NOS TUBES ★ You must like:

Click on 3) Equipment feet

Then a chassis can almost float on a magnetic field.

That's an interesting take on the Sigma 11 regulator. Looks like it makes some worthwhile improvements.
I am using four of the Sigma11 in a DIY Naim dual HiCap to power my NAC 82 preamp. I started with just a pair to replace a factory Olive era HiCap, and the improvement over the Naim implementation was very worthwhile. Adding the second HiCap worth of regulators took the preamp to a whole new level.
