Sony VFET Amplifier Part 2

[dady]

Recently I got decenies of VFET, 2sK60/2SJ18 they were all fakes. Thanks I got them by paypal but is necesary show evidence for get the money back.

Count me in for the kit with dual pair. Hope Papa can
Allow me to copy his build including the chassis....

I'm in for a kit! I think I'm only one or two amps away from no longer needing the furnace for central Pennsylvania winters!

Here is something similar to the Sony-VFET-2 using IRFP240 and IRFP9240 output devices. The front-end also supports cascode feedback, but has bias circuits more like the F4. I am still "tweaking" its sound.

I too would love a dual pair kit.

Good point! A current follower.

I am working at this point to produce a front end board that would be acceptable to eventually go into the diyaudiostore. The backend of it I think will come later once the dust has settled a little. This is of course if papa approves, or has nothing else in the works.

I would save me the trouble, and I can use the time for some other project.

I would love to see a SE single P channel schematic from Mr Pass maybe along the lines of the SIT1. To my knowledge no one has the capability to produce an amplifier like the SIT1 and DIY will never have access to Pass SIT's. It would have cost $300,000 according to Mr Pass to have some made by Semisouth and now they are our of business. This will be the only chance for DIY to make an V-fet SE amplifier in the near future and presently the available V-fets will be gone. 10 watts is plenty for a lot of DIY'ers. I can understand not wanting to share proprietary information if he chooses not to do so.

There's at least 3 SE V-Fet amps.

Check Michael Rothacher's site, the author, for addendums.

With that said, I wouldn't mind seeing more variations. I have 10 2sk82 and quads of 2sk82 and 2SJ18s.

The L'amp 6w CCS SE is fantastic and I'm glad I didn't sell it for parts money.
Close one. Even better with CLC power supply filter.

Please take me ob the List for a kit....

Hi,

And I would love to get the output stage with 2 parallel v-fets.

Thanks, Dirk

Maybe we can do a group buy at Aliexpress???

I should have said "Pass inspired." I am familiar with Michael Rothacher's site. I check it out often and have considered building one of his designs. Very talented individual.

 

[vdi_nenna]

They are Pass inspired.

Ayway...good luck!

 

[Michael Rothacher]

They are Pass inspired.

Very much so. I credit Nelson for all the smart bits.

And, if you find any dumb bits, those are mine.

P.S. I really want to build this one so count me in on kits or PCB's or whatever, and I'm happy to wait at the end of the queue.

amusing one ,besides that

 

[wdecho]

I am indebted to all the talented individuals on this forum. I am looking forward to a schematic using the V-fets still available 2SJ28 P channel. I ordered a couple 2 days ago before they are gone and I already have 2 pair of 2SK82 and 2SJ28 for a CSX1 build. I have put off building the CSX1 until I decide if I want to build the V-Fet 2 and when boards are available.

Am I wrong to assume that there is a great deal in this article that has nothing to do with Vfets?

no , you aren't
