Article - Sony VFETs part 1

[Zen Mod]

hardly - if you're going with predicted Iq , including losses in regs , you're still good

if you're near 60C at summer , add some breeze , et voila!

though , one 70C breaker situated in center of case, as Papa does in FW amps , will suffice general protection duties

 

[R-K Rønningstad]

Hardly what?
Anyway, I think the SK139-200 will do.
BTW our German friends have some useful tools
here
and here.

hardly that you'll need (with those heatsinks ) to:

......... simply cut the mains.

 

[R-K Rønningstad]

Ahhhh, Mighty One!
I see.
Remains to be seen if I can stuff all transformers and capacitor boards etc inside. Pictures to come, but do not know when!

 

[Zen Mod]

don't use force - take a bigger hammer

make bigger case

go deeper - add some wood or metal sheets to heatsink sides

My favorite moment of the year
new amp diy article from Papa

 

[hifibluedevil]

wish I could find a source for 2sk77/2sk77b, searched everywhere. I bought bunch of 2sk82s and 2sj28 from circuit.diy though so I can make Vfet 1 and upcoming Vfet 2, and may be iron amp. Looking forward Mr Pass's new article.

That's good news! Love to build the matched two pair version... The CSX1 VFET amp is still the amp I listen to the most...
Almost finished with the rebuild of my Aleph J so end of the month will fit very nice

[vdi_nenna]

We'll find out soon enough hopefully.

NP has to do something fantastic with all the SITs he has....

 

[Zen Mod]

PapaSits ...... certainly , but I'm doubting that he collected ancient ones enough for trouble-free production
