Thomas, it looks like it would be easier to add this feature to your own gain stage and see what happens. 🙂

Hi!
I admire and respect Sakuma's work a lot. But I do not follow all his principles. I am seeking a different goal in terms of sound than him. He did inspire and influence me a lot though. For example with his use of DHTs as drivers and in preamps and with the use of power tubes as drivers.
As far as I'm aware he is not selling his amps. At least not at a scale which could be called commercial. Implying that there is a marketing agenda is therefor not justified. I also don't think that his use of Tamura products makes a noticable dent in their transformer sales.
As others have written, Sakuma is not stupid or ignorant. I am sure he had a good reason to do this and I would be interested what he had to say about it. If he wrote about it then in MJ magazine, to which I have no access.
Nobody out there who read about these circuits in MJ and can share what was written about them?

I have read that he never courted followers for his designs, what he wanted to inspire in others is to guard against allowing today's, past or future 'conventional wisdom' from constraining your approach, to try things out even if they might be counter to what you'd expect, and ultimately tune your amplifier for you, for what you like. As I understand, the last thing he would ask is for anybody to build somebody else's amplifier.
I thought he is no longer with us though - does anybody know ?

That sounds good. To tell you the truth, I don't know much about him. I have no idea where his fame comes from. A flagship amplifier? Articles? I'd like to hear his system but that's not gonna happen. Anyway, those weird 'ideas' will remain weird ideas. I can't imagine anyone here trying them out.
Audio seems to have become like the art world: the value of something seems to depend on who did it, rather than any intrinsic merit of form and design. If I put out a circuit like that everybody would rightly (and very promptly) tell me it was rubbish. Far east guru puts out the circuit and everybody worships; they assume that their own concerns about it are merely a sign of their own ignorance of the deeper things of audio. "He must have had a good reason for doing it that way".

Hi!
Nobody worshiped these circuits and Sakuma is a very modest man who would not see himself as a guru. So why this angry attitude? Sakuma's circuits receive more cynical responses than worhsips. And guess what, he probably doesn't care.
All I was interested in was what he himself said about this, if anything.
Best regards
Thomas

Maybe you are thinking of Nobu Shishido, who developed a series of A2 single-ended amps using transmitting tubes.

Three or four decades later, Tom Wolfe's _The Painted Word_ is more relevant than ever. But now, it applies to everything.
Thanks,

The "Teacher" Sakuma, said that: -for an unknown reason to me, adding irons betwenn the stages help the tubes sound better-. He uses series connected transformers to match the signal as he also uses series trans to achieve double voltage for the power supply.
This trick it really works and it sounds maybe better than single transformers do!
Becides we also do this to the electrical enviroments...
Of course there should be lots of theory arguments to this, but the fact is the transformer's action
and behaviewr differs at the working position, so please no comment to the subject.

I have nothing to add to my previous comments. This thread contains wisdom, but it doesn't come from the fanboys; they are still puzzled.tassis said:
Active hum bucking circuits. As to why Sakuma would use the audiophool expensive types for this makes no sense, especially when vertical deflection triodes, or pseudotriodes from the 6AQ5, 6V6, or other 6V6-oids, would work just as well for this purpose. Since he's iso-ing both inputs and outputs with ISTs, he could have gone solid statey here and used a MOSFET.
You've missed the point, he's cooking and seasoning to taste, hence his choice of ingredients. 😀 😀
The Japanese are very passionate and artistic people. So much so they experience passion mainly esoterically with a sense of embarrassment when in public. Its a very different culture.
I'm with DF96 on this. The thinking that these circuits represent the discovery of some deep, unknown audio phenomena is total crap. This is the same kind of thing that sucks audiophools into spending $2000 on speaker cables, Shakti stones, and Bybee conditioners. 🙄
