Dont worry, I knew that allready😀 No need to hurry at all. But do you find the idea, any good? I mean, I thought it was a great idea, swapping out 78xx and 79xx's with small plugin shuntregs!
Maybe it is just one of those things that just sounds too good to be real?

Hi Choky
A little bit of topic my question but I trust in your opinion and your knowledge so I would like to ask you if is possible to modify these schematic to balanced mode how you did with your Aleph J .
Please let me know .
If yes what is your advise .
Thank you very much .

Hallo Gabor,
very interessting schematics,
have you ever built this amp?
The 2SA606 is hard to find, what is your substitude for this transistor?
With kind regards
Sam

HI
I collected all the available parts , to replace the A606 transistor I will use BD140 .
These amp is a Japanese design , I would like to try it .
I read very good comment about .

I´m moving over here from the Aleph h thread. It´s an old thread but I´m planning to build a headphone version of this amp and I have a couple of questions:
- Regarding the schematics in post #690. R17, 21, 22 and 23 are marked 1E2. Would that be 1ohm?
- It is suitable for high impedance headphones <300Ohms?
- If I understand the schematics correctly the input jfets are the only transistors in need of matching, correct?
Best Regards Christian

-1E2 - European for 1R2 , meaning 1.2 Ohms
- why not
-yes ; as I wrote in that other thread - they're either one 2SJ109BL ( unobtanium) or pair of 2SJ74BL , or newest LSK74B

Hi!
First a late thanks for your quick answer. I have a lot of matched 2SK170bl and it got me thinking. It is possible to simply swap the polarities of the schematics and swap the transistors for opposite polarities?
It is possible to do the following:
1. Swap the polarities of the schematics.
2. Replace Q1 for a matched set of 2SK170bl
3. Exchange q2,Q3 from bc556 to bc546
4. Exchange q4 and q5 from bc546 to bc556.
5. I plan to use it as a headphone amp so q6 qnd q7 would be IFR9610

it's done already somewhere on the forum
maybe is better to chase few dozens of J271 and use them in schm as is

It's apparent that Pao is backwards, and really doesn't like p-channel power devices. (especially the hump-backs) 
Thanks for a quick answer!
I think i found the thread you were referring to, "Inverted" Aleph J? I want to experiment a bit and the j271 doesn't seem to be easy to come by either. So by using my 2SK170bl i can build prototypes cheaper and easier. As i understand it the inverted version will not be sonically worse.
