Ono - 2SK170, Which Idss?

[transducer]

Which Idss classification is best for Pass Ono, GR or BL? This is for the MC stage. Which classification is best for general work? I plan on building the Ono but also some other phono stages.

Thanks,
RonS

That's an interesting question, I was actually wondering about the same. Any J-Fet experts out there?

Hi folks,
You might know Erno Borbely a colleage of NP in writing
for Audio Amateur (now Audioxpress). He´s a JFET wizzard

NP uses the BL variety.
I bought 2 sets of matched 2SK170BL's and 2SK389BL's for my Ono phonostages from Erno.
He is a very nice guy and offers excellent service.
Sometimes he answers the phone himself. Why don't you give him a call?

Due to the Article of Erno Borbely i have put the BL-Types
in my Phono-MC-Stage and i have matched them self.

That's an easy one..........

Always go for the blue.

Yo Jocko!

Where ya been buddy? Glad to have you back

So I need them BL variety. Too bad, I have a lead on a bunch of GR type for a good price.

Well Peter, guess we have our answer, don't we?

Cheers,

I might be interested in the GReen variety......
Where did you find them?
Or we can eventually exchange GReen for BLue

 

[Jocko Homo]

You can put the GRs in paralell if you need to get the transconductance up. Yeah, the bandwidth will be a bit less, but there are ways around that, too.

Massimo, drop me a mail and I'll see what I can do for GR flavour for you.

And since Jocko missed my offer to his pizza friend Phred:

Jocko, if you need any Toshiba 2SK170GR please let me know. I might trade it for some good advice later but if you can spare that we may have a deal.

 

[dorkus]

somehow i don't think jocko is in need of any GRs, or any other device we can easily get our hands on for that matter.
actually what we really need to do is go down to texas and twist his arm until he gives us some of the JFET goodies he's stockpiled. you know which ones i'm talking about jocko.

 

[mlloyd1]

Was that my cue to start whining about some V grade JFETs
So, dorkus, when do when leave for Texas?
