This amp is complementary (push-pull) design. I will try later in quasi-complementary design but I have no candidate yet...
Every quasi-complementer (less stages, only one complementary-stage, ONE psu - se-psu,-? -, not a complementary-psu) will sound much much cleaner than every complex complementary-design (some, many complementary-stages).
Just build anyone and enjoy.-)
Any circuits I had found here:
elo.maanders
The class A, exacter se, on this side, sound much much cleaner than every quasi-complementer,-)

personally I have yet to find a CLASS A amplifier that does not have a weird non musical airy sound....
sounding good (your class a) versus sounding like the real thing (HK430 class AB) are 2 totally differing things
I respect what people like but I am looking for the REAL THING. and so far HK430 is tops!
there are many things that sound good nice pretty etc ....but I want something that is better the average or good amps out there...
if your close to where i live I can give a demonstration of what im taking about ...🙂
The old Harman receiver, HK 430?
yeah that old crusty HK LOL....
there is no amplifier i have heard surpass it!!
that is if you know what real un amplifed music sounds like

BTW if you build the HK use the toshiba drivers not the nec
there are many iterations of the HK and the best ones use the toshiba drivers this is a secret ...

Not very bad,-)
Quasi-complementary. Two pp. (-?)
Use not the pre-amps. The real thing will sound much more real. New-solder everything - much more real ...
Final you will get a se, with much more solition - misunderstand as "no deeps", musical airy sound ...
Use other speakers than.

I have IMO best speakers very wide bandwidth!
my speakers are wide band 8 way....13-100kc...they do not ring or impart a color if you will.... but will protray everything in front of them...
its not the speakers its the amplifiers that are not that great ...I have proven this time and again...
again I have not heard musically correct class A amplifiers

Hi Guys
I doubt your speakers are "8-way" as that would mean a crossover with eight points of division. I would suspect there are eight drivers and possibly up to four crossover points. In either case, your system would benefit from multi-amping and the use of an electronic crossover. This reduces total system distortion by as much as 80%. Multi-amping also eliminates tweeter burn-out.
Have fun

Hello Thanks for posting...but your wrong! don't believe me? let google be your friend!
there is 11 drivers in my speakers...with 5 tweeters of differing ranges!!
8" midrange 10" upper bass 12" lower bass and 2 12" sub woofers per speaker!!
I have played with bi-wiring as this speaker can do...but Im not a fan of using terrible sounding electronic crossovers...whats in the speakers will be far superior
Seems a bit over complicated.
You didn't test the amps with different speaker?
yes in my system and my friends at the time class A amps sound weird airy but not real!
The speakers are your problem. In my mind,-)
Sooo much problems ... you need this amp to force a "play together".
The HK 430 is, my mind, a good device. Some to try, to proof. A real big chance to learn a lot. I suggest to "remove", to bridge some unnecessary amp-stages, to new-solder, to control the psu, may be, to replace. The power amps do use channel-separated psus. Exacter two times two. The first I would alter into two. Connect these two times two to two (+ left with + right channel, - left with - right channel,-)))
My first suggests.

Have you heard my speakers? I would think not they never made it to your country
How can you speculate with real emperical experience with my speakers?
Let me say I regularly hear 180 thousand dollar speakers not including other electronics and although I can see why people like them they are no where in my speakers league hell IMO there is no other speaker capable of reproducing realistic sound we hear live ..no it's not perfect BUT its more perfect then all the rest IMMHO
And that's all I'm going to say about it ...if you want further information about the speakers please contact me through PM

Link? There is nothing I can find to tell you how many drive units in the premieres or how they were connected. It would appear that they are 40 years old which is all I can find out.
Surely you must have written a review on them, given you keep offering to write reviews on amps in return for free samples...

what did i said above 🙄
All 180.000 Dollar speakers are katastrophal,-)
Your HK sounds much much better, cleaner, than all "super-amps", whether Accuphase or Krell or others.
I have seen your system. That is enough. Trust me, this is a chaos-complex. Use only the mid-speakers, some stands, remove the subs and highs. Try a lot with damping, build in, may be cables, connectors. Get appetite for more/less, cleanness,-)
