I do know why it is necessary for anybody tell you anything – use your own judgment. Leaving aside the advantages and disadvantages of transformer coupling use you own common sense to think about the bandwidth of the transformers loaded with se...

I have visited Sakuma's restaurant myself.
You don't need to travel to Japan to know that stock Altec A5s and Lowther-based designs from the 1960s basically run in the 70hz-12000hz range. They are in mono, and not particularly well-placed. That is...

[quote user="guy sergeant"]After post #1 I was wondering how long it would be before post #5 appeared. It did not take long![/quote]I got the email with Sakuma’s film and posted it on my site. Are you blaming me that I am familiar with Saku...

I suspect that Mr Sakuma might likewise not find much inspiration in your system Romy. I also have suspicions about the real motives for starting this thread but that's another issue!...

It only uses Cogent f.c drivers .Josh Stipich from Electronluv is the designer/maker of horns and amplifiers and Cogent role is secondary (my guess) . Electronoluv aproach is afected by Sakuma designs and using lots of transformers&nbs...

[quote user="drdna"]But how can you make the Melquiades as a DHT amplifier? I do not see it. [/quote]
To make Melquiades as DHT is very simple juts use DHT output tube. However, if DHT idea does make sense then I think the diver shell be DHT as well...

say how much the old man is involved in all this cult and noise around him? I've also read all the poetic stuff on the site and can't say that this mystical aproach is not appealing. I had the impression that Sakuma just entertains himself makin...

It is entirely possible to find and develop something of relative value working with a challenged toplolgy, even if the limitations of the topology dictate that "ultimate" results will fail to reach the Aural Summit.If you hear something that wo...

Romy, It seem what with the tacttile pleasures of boiled egg potting compound sensations you are going a bit Sakuma yourself.I will say this: I think Pieter is an absolute magician when it comes to iron; he's also a gentleman despite looking lik...

I've read about what Sakuma does (as have many people) I've never listened to, or tried to build any of the amplifiers he publishes schematics for. However, I have made several amplifiers which use interstage transformer coupling and, provided ...
|
|
Yes, Sakuma seemed to enjoy delivering some It via "old methods". But he was able to do it not because he used the old methods but because he could use his ears to home in on It. For many years I used Fulton speakers, and Bob Fulton was another one w...

My mood swings around this Remedios project are remarkable. Literally a few days ago I meant to trash the whole things and start from scratch and now I again am super enthusiastic, unhealthy enthusiastic. Paul was right to fix 6-in baffle will be pa...

It you do not care to read my bitching then watch this Sakuma clip. It shows off very nice the Sakuma’s “deliberate mono” solutions. Be advised that they use very wide angle optics…. The caT...

Hi Romy,
I happened to visit your site and stumbled on the Sakuma discussions.Just in case anyone was wondering what was being said in the two videos:
1 despite looking like a vampire, there was no religious cult like talk. No mention of spirits or...

Romy,
But how can you make the Melquiades as a DHT amplifier? I do not see it. But otherwise you will be comparing the tonal characteristics of just different topologies and parts, not comparing DHT to IDHT. If this is the objective, then I th...

[quote user="Romy the Cat"]did anybody pay attention that all coupling transformers-loaded amplifiers (among those that I heard) sound in a similar way as the amps with high voltage output tube that run over 1KV on plate. Did you ever think why?[/quo...

...but it will take me N-years and I'm in EU :)I could make some preliminary steps this Easter, talk to my winders about transformers etc.I'm for sure missing the FW and out put cores (AMCC800A will not support 120H at 300mA, low DCR), but getting ma...

[quote user="Romy the Cat"]So, Teflon, I do not think you got what I meant. SET has no 'topological limitation' because exists DSET. DSET is free from any, even theoretical limitation, of cause if you prepared to deal with price and power demand...

[quote user="drdna"]I wondered if Romy or anyone else has toyed with Sakuma's very interesting topological solutions. I have followed this for a number of years but my circuit building skills are so poor I figured I would likely blow something ...

FYI
The news
On Sunday, December 13, Mr. Sakuma who was hospitalized due to poor physical condition passed away.
Wednesday, funeral

Hi Romy,I see why you don't like the design. And in particular, the choice of where he chose to limit the frequency responses for the two channels. I see the benefit of the DSET approach in this context as you explained it. If I understand you, your ...
|
|
[quote user="drdna"] Would you then suggest that this approach demands the DSET approach to succeed? [/quote]
The DSET resolves all problems with SET amplification; it is not surprise that Sakuma went there. BTW, my familiarity with Sakuma’s DSET wa...

Kids, do not let kids to subscribe the popular audio-freakish myths of the records spinning people about “the extraordinary beauty” of the Denon cartridges. Yes, the myth has some reasons: many more expensive cartridges are bad, very bad for th...

Roman,[quote user="Romy the Cat"]Nevertheless, if that bass was truncated between the stages then the devastations are way more severe. [/quote]That may be so, however an LF response of less than -0.1db down @ 10Hz is what is normally called "ruler f...

I was thinking about the obvious disparity between the
“sound of live music” and the times of special involvement with Music that I’ve
experienced over the years, and for decades I have been turning these notions
around like puzzle pieces, try...
