WTB: Genuine Toshiba 2SK982 / 2SJ148
 
Please let me know if you have some for sale.

I'm looking at 2 - 6 pairs.

Thx

Try B&D Enterprise they had some of each of them last night

Thanks for the info.

I'm trying to see whether other diyaudio members have some that collecting dust, before I go to the B&D Enterprise route.

I have some- What are you building? Borbely power amp ?
You can build Borbely line amp with only 170/74 and 216/79 outputs.
I only want a Tag Heuer Carrera for them :D

Hi ticknpop,

I'm building a borberly shunt regulator to replace my JC-1AC pre-preamp power supply which was busted.

And for the future, I would like build one to three shunt regulators for powering BIII DAC legato I/V converter.

Unfortunately, the carrera is not in my radar :-)

You could replace this complemantry FET pair with a high beta BJT pair without any problems...but you`ll have to do some small modifications to the circuit, it shouldn`t be a big problem to do..Even 2SA1015GR/2SC1815GR would be a reasonably good substitute.

Thanks for the info. But I'm just a noob who doesn't really know how to modify circuit.

Basically what I'm trying to do is to build a shunt regulator power supply based on pcb from Jims Audio.

All FET low-noise super shunt regulator PCB Borbely ! | eBay

Well ..Then that`s one of the only sources still available to get these genuine parts.

I build Borbely shunts too (original pass devices were 2sk2013/2SJ313) .
I can sell 6 pairs J148/K982 for $55 with Canada Post included. Not cheap, but cheaper than BDEnt and I really don't need to sell them, because I will build a few more Borbely shunts for a BIII Dac also ( with Borbely discrete jfet I/V converter also powered by Borbely Shunts) They are used in the Borbely Millenium Power amp too that I have, so I need to hang on to a few spares. Do you have 389/109 for input differentials ? I wouldn't use 109 here if you could find them. Even matched 170/74 are getting hard/ expensive to come by. I stocked up years ago before the great jfet famine.............. Even have the very low noise 2SK147/2SJ72 for phono inputs that I got from Erno 20 years ago :eek:
