Well, I searched for both "bom" and "parts list" and didn't get results.

Thanks, don't know why that post wasn't showing up in a search.

I deviated in several places from this BOM: First off the 500Ohm pot needs to be 1K for the listed FQP's. Secondly the 35V SILMIC II's for C3,4,5,6 don't fit the PCB, as they are to wide, I went for the 25V once. Also I personnaly substituted the 1x turn pots for 25x turn pots, as they are far easier to dial in.

This may have been mentioned in earlier posts, but I what is the maximum rail voltages for the circuit?

 

[Soundhappy]

+/-30 V DC max

See page 11 of the DIY Sony VFET article for more on supply voltages.

Sony VFET PCBs – diyAudio Store

Vfet Sony Diy Amp pcb's are back in stock

TO-3 brackets too! UMS compatible TO3 mounting brackets (US warehouse) – diyAudio Store

Sadly the TO3 brackets are not back in stock. We may do more of them in the future though.

And when will the V-FET be in stock ???

 

[Nelson Pass]

It is currently in stock on my shelf, awaiting completion of new design for DIY.

Any chance of buying a set of VFET transistors?

 

[WBS]

It is currently in stock on my shelf, awaiting completion of new design for DIY.

Is this the long awaited, highly anticipated design to utilize all of those Sony SJ28 vfets we horded last year?

I believe Nelson said it can be made with any vfet. it will be very flexible in that sense.

We want information
YouTube
we know who is the number one

 

[Stanney2017]

I just ordered the VFET PCBs which are back on sale.
Where can I find the VFETS?


Best.

Sorry for asking this - Im sure the answer is here somewhere - I did a search & couldnt find it however - is the minimum impedance 8 ohms? I couldnt drive a pair of KEF 104.2's with this? Probably not I think (also as these speakers need a bit of power to drive them). Cheers!

Also 4 Ohms are fine, with slightly bigger power.
