B1 with Korg Triode

[jostwid]

And i particularly love Papas choice of electrolytics in the signal path

 

[MEPER]

Probably Silmics or are they upgraded to green Nichicon?
We will see how much space there is on the PCB to upgrade to e.g. MKPs…….

Papa clearly chose to use electrolytics (looks like Silmics or Cerafine). He not even left space for the alternative on the PCB.
I take it as a message and read: "Look i am quite happy with that.."

As usual, I have boxes of the older Silmic parts. It looks to me like the
Nichicons would be a good replacement candidate.

B1 KORG KIT

I am interested too. Please put me in the list.

I don't think there is an official "pre-order" list yet? You just act like there is one?

 

[a3cervo]

@MEPER - the guys just can't contain their anticipation and in line with that, please put me on the imaginary (for now) list

 

[Nelson Pass]

We'll have some info on this after a bit.

 

[Chul]

Yeh~!

We'll have some info on this after a bit.

My expectation is high, especially for those follower amps including SIT3. It( wa)'s Papa's birthday and I believe this is not empty promise.

 

[MEPER]

Will there be any change of the schematic for the DIY version of the amp?
The output impedance is 221 ohm? …..would it be possible to make an e.g. 50 ohm version?

 

[Nelson Pass]

I am attempting to have focus on one thing at a time.

It's not easy.

At the moment there are about 15 things on the list.

 

[MEPER]

15 things…...then we will wait and see……….

Keep in mind that Pete Millet has an evaluation board on ebay for $100.

and there is a 15% off coupon for anything on there that ends today: PERFECTDAY

No equivalents to Papa B1 Triode 2H pure tone audio work and elegant boards

 

[MEPER]

The input and output buffers are also very different compared to the PM version. I am looking at which attenuator I may use for the amp. Never tried a shunt version where only two resistors are in the signal path on all settings…..

SRPP preamp made with Korg Nutube ? SRPP+ Part Two

 

[Nelson Pass]

The Korg Nutube has a common ground on both cathodes, so you
would have to deal with that.

 

[Soundhappy]

Oh I see two Korg's for mono SRPP channel ?
