High Fidelity Tube Amplifiers Build, 99% Made in India…

[Analogous]

I just thought of a second independent set of reviews. Not a review of my amp or ALTEC VOTT A7-8 speakers, but of my unique power supply design which my Mentor and I term as " L.S.E.S. " ( Low Stored Energy power Supply )

The two reviewers independently shared their personal results of building and listening to what I had introduced publicly, and advocated in 2005-2007 on the Audio Asylum USA Forum. I believe both these individuals have EE degrees, and for sure - both are highly qualified, advanced, audiophiles. One, John Swenson, was using Lowthers, and the other EE John L. Hasquin was using his own engineered adaptation of Tom Danley's " Synergy " single point-source horn-loaded speaker system. Obviously, just running what they were for speakers, neither of these two fellows can remotely be called " neophites " !!!!

In a recent HFV post, I invited people with curiosity to LEARN, to write to me, and receive a orderly-compilation of each E.E's /Audiophile's posts, regarding their build and listening experiences with L.S.E.S. Guess what Analogous....my invitation fell on death ears. Not a single person to date, no F.M. on H.F.V., , has requested to read about their posted power supply building and listening experiences.

This lack of human curiosity, to learn something new about audio design - from qualified others, is something that strikes me personally as being fantastic. Actually rather stupendous, given the vast size of H.F.V.'s reading audience.

Analogous, using H.F.V. you can P.M. me, and I will arrange to have their compilation sent to you for your perusal. 'Same for anyone else. Thank you for asking.

Will you ????? - become the first person, to review their results / conclusions ??

Many can learn some great things from their own previous independent build efforts !

No one has to take my word for it.

Thank you Jeff. I would like to read the reviews if they are not very technical. This is because I wouldn’t be able to make sense of it given my limited knowledge of electronics.
I am definitely interested in reading subjective opinions of the sound specially if the reviewers share some information on the partnering equipment, music listened to and a brief description of the room.

Easy, yes people will have to trust me 100% on the circuit choice.

The average EE will not be able to grasp a JADIS JA30 much at all IMHO. IME. It is an artistic audio design choice, of a higher order, an amp that would truly allude the typical audio technician !!!

IF this gets done, we will design the audio section inspired by French Jadis JA30, with me re-doing its power supply - doing a fully PSUD simulated supply. The JA30 is a many years proven to sound lovely circuit, with TONS of Jadis Owners subjective reviews.

Review for yourself many of the owner's / user's on line comments on Jadis JA30 and Jadis JA30 MK 2.

It would be my yet started brand new initiated thread, for the benefit of interested HFV F.Ms, . I get to specify and choose all the specific parts, Manufacturer, Model, and acquisition source.

Two Monaural amplifiers, EL-34 output tubes used. The French build somewhat lush sounding audio gear, not syrupy, but capable of eliciting the emotion, associated with the original music's recording.

I have not yet sourced schematics. on the later " MK 2 " model, so I have not started ant separate thread. Can anyone assist me with a schematic of a Mk 2 with voltages ?

At least two eBay Hong Kong suppliers exist for an audio PC board. eg :

The earlier audio schematic, with design subtleties which intrigue me no end, is as follows,

Notice circuit !!! The input ( buffer ) stage is directly coupled to the driver stage, and only ONE cap couple ( encircled ) in the entire amp. KISS rules!!

Need to find and see a JADIS JA30 MARK TWO schematic next. Can anyone help me?? Subjective user's reviews are superb, listening - wise.

Here is a subjective video discussion of my ALTEC VOTT A7-8 speaker system for you to see and hear. As I have set-up mine at home, I love it !!

I use my ultra high performance AMPS on mine, my latest, and it is COOL to hear. Still a work in progress, since 2015 OHH, the 3 HY choke in Reichert's video-pictured 300B schematic, is a result of me personally " baptizing " Herb into low DCR back in the 1980s. It was from Fair Radio Surplus Sales. $7.00 each surplus- priced, 24 ohms total DCR, or 8 Ohms per Henry. An earliest attempt.

If you are in Chennai, You can listen to my DIY SE amplifier. 6watts

Do visit AVlounge in Kilpauk. He has some exceptional tube gear and other allied electronics including turntables and speakers. it can be a nice experience, especially for DIYers.
