By any chance, is there another set of front end ant output stage boards available?

Yes there is. I think all the major parts are still available.

I am currently out of boards.

I am going to do another small run of them, as some have been able to get good pairs from the diyaudiostore GB.

On that note, I have some extra VFETS I am trying to make pairs for. So if anyone has any spare 2SJ28 parts, let me know. I wish to buy them and try to match them with my stash. If not, I will have some singles to spare for both N and P channel parts.

There are a few people who have asked for them, as they were able to obtain some pairs out there, and want to make the paired version.

So if you want in on this GB, let me know as soon as possible. I will be closing the GB on 11/20/16

I will sending out Private messages to the people who have shown interest.

Tea,

how does your circuit compare to the kit version they are currently signing up for in the main thread?

I have no vfets and my concern is if I have to buy the complete kits now to get those?

also: how does the original version with 2 pairs per channel compare to this one? would your pcbs still be usable? (sorry that I did not do the homework).

I need min 30W/ch@8ohm and my options are either the 2 pair per channel version or to run these single pair versions bridged with a balanced preamp (not sure what that would add up to in terms of noise and sound though).

This version compares only to the original Sony VFET version 2 design Nelson originally designed, and requires 8 VFETs total, 2 Matched Pairs of 2SK82 and 2 pairs of 2SJ28s.

If you do not have matched pairs of VFETs, this board set if not for you!

I have not listened to the single paired version for comparison, but I have heard it it very close in sound, but not in output wattage.

Got it. THX.

I am also getting caught up on the threads and I have already answered my own questions. it is your board that I would need if I was lucky to get the matched vfets in sufficient numbers. the issue is the kits built around the single pair version have the advantage in diyaudio store, so I shall have to wait and see.
