It will run either way. I'd put the feedback on the other side of the output resistors, which I gather is what Nelson is actually doing.

Can Nelson's Schematic be used as is or is the feedback incorrect?
Thanks,

Papa sez that you can use it in both ways

JEKYLL said:Yes, it seems easy to modify the original Aleph circuit but I can't find 2sj109bl.
Where do you buy your 2sj109bl?
I'm going to use matched 2SJ74BLs...I have a pair of 109s from Steen but those fragile little critters won't handle my supercharged output...they'll be put to good use on a straight-up AJ someday.

BTW, the question was also purely arbitrary...😉 (IOW, random stupidity on my part)

What makes you think that 2SJ74 is any different ?

Because I can easily parallel them...tell me why they're not. That's not to say you can't parallel 109s but for me who handraws my circuit boards...it's more difficult. If I design a ckt board would etch one for me?

Exactly.
> but for me who handraws my circuit boards...it's more difficult.
one can of course solder one 109 on top and 1 on the bottom of any PCB without changing the layout.

I remember that I saw that on one of numerous japanese constructions ...........
just one thing to add , regarding solo vs. dual thingies ........ besides my past troubles to find 2SJ109BL in any decent quantity , and that they not cost arm and leg ........ I have one more thing pretty important - I still need some money for da toobz .........
ya remember that they have more legs than these 3 or 7 legged fuses 😉
just my opinion and xperience .........

Does that not promote your status to God ?

if you say so ;
but not God , just Saint Alexander of Batsch .

I have a hard time accepting EUVL to even think of doing that...
My requirements require more than just 2 diff pairs in parallel...please don't ask why as I know you know why.
St. Alex, please no OT!

Maybe the Saint can explain why the amp will stampede if R27 is removed instead of becoming an alternating flashlight ?

tell me that on plain Engrish , and then I can tell ya why is C2 there

10-4, i missed the supercharger, the problemo with us heathens is that we look down on a schematic, never up.
As the Coën Bros before editing made Cedric "Gus Petch" say in Intolerable Cruelty : Messiah, I'm gonna nail your azz.

The Master is so busy with reading physical stuff and camouflage architecturals, he should have a master's voice to do the drawing labor.
