Hi guys. I have reached to end of my diy audio path and I sell some nice things. So, I have one HP3580 in good state, working; one HP 8903B working too. And I offer two nice sets of transistors... four vfet sony 2sk82 tested and one 2sj28 (tested but I have not data when I did it). And I add to batch two 2sk183V. On the other hand, I offer four SJEP120R063 (fantastic for clonning of J2 or F2J).
vfets set ...... 250 eur + shipping + fees
SJEP120R063 ..... 240 eur + shipping + fees
HP3580 ..... 300 eur + shipping + fees
HP8903B ...... 300 eur + shipping + fees
vfets set ...... 250 eur + shipping + fees
SJEP120R063 ..... 240 eur + shipping + fees
HP3580 ..... 300 eur + shipping + fees
HP8903B ...... 300 eur + shipping + fees
Ahhh, I'd take the VFETs... would be great the increase the Sony VFET population of the group buy a bit more to get more matched pairs.

What is the difference between SJEP120R100 and SJEP120R063? I have a small number of SJEP120R100. If they could be mixed/matched/paired with SJEP120R063, I might be interested in your SJEPs.
SJEP are something special. With them it is possible clone J2 (I do not know how do it), or build the F2J (I did it)
Ahh, the 120R063 is a very nice part then! But it does not make much sense to mix/match them with 120R100.
No kidding! Some 10+ years ago I had a little side gig for a while where I'd buy HP 8903 on the used market, fix them up, run them through the performance test, and sell them. I sold them for about $500-600/each.
The 8903B is pretty rare. Unlike the A version it has a true differential input, which is nice. It also features two slots for filters that could be preconfigured by HP.
I think I had 4-5 HP8903A cross my bench but only one 8903B. Both are great instruments. They'll usually get down near -95 dBc THD at 2 V RMS, 1 kHz.
The HP3580 is a classic.

Hi Tom. Thank you for your comment.
You are the reason I leave out diy path. Your Mod86 is fantastic and it is the perfect match for my ESL86s
Eternally grateful

Hi guys. Thank you very much for your offers. Let me some days for performing packets and go to ask for shipping costs
Later a lot of years building stuff, I have reached two good setups for me. One with pp tube and ss amp and ESL57.And other one, with SE, one 45 tube and other with vfet amps with nice full range driver...
With my budget I can not improve neither, so, I stop and I offer you, at reasonable price, my stuff. I think never I will use.
From now, I hope enjoy with music. I discovered that I lost the main target of this hobby.... Music
