I would give DOGC a try. It is a variation on a QUAD Current Dumping theme, low parts count, pdf for pcb is available (both low power and high power version), specs are fine and many people made it.

Hi...dear Thimios
May I suggest you a Calor Gold amplifier?... I built Modus amp, but IMHO I prefer Calor Gold amp... but Calor Gold is a 40watts Class A amp... very power full low kicker... or you can try to learn about Sigma amp.
I am in the way to build the 2nd Calor Gold amp for my friend after he got DR. Jagodic's permit.
Best Regards
Arif B

Default Techno, or something alike.

Well... all designs from Bora are great.

Borivoje Jagodic is an Universitary, a College teacher, ....he teaches design..... audio design.....

Got it?

He is the man... we are all people filled with curiosity....he is the man!

But there's a problem in this stuff....Bora always thinks people has enough know how not to overdrive, continuously, the amplifier while injecting square waves..... his designs are rational and do not suppose we can make foolishes..... all amplifiers can pop out if we manage to destroy them.... their amplifier are made for normal use... rational use.

I remember, once, a good friend that injected square waves, overdriving the system....you know, square waves generates a lot of harmonics...it is almost a short into the output...in the flat lines you see, the horizontal lines, what you see is DC from the supply...so... transistors saturated....all the current the supply can provide will go to the load crossing the output transistors...and as all of us know...when shorted, a small transformer can deliver a huge quantity of energy, several amperes... then the amplifier was damaged because tortured...and the guy became angry against Bora... was not fair his judgement... as Bora cannot detect, in advance, all kind of foolishes when can do.... we can reduce impedance...we can use passive crossovers with valleys of impedance.... we can have highly reactive loads... we can install small heatsinks inside a closed case, without ventilation...well.... we can kill almost all amplifiers....and the defect is not the amplifier...the defect is inside our mad mind.

Bora Amplifiers are made for music, not for noises, or continuous generated crazy tones, distorted continuous signal....it is calculated for music...if people may overdrive, or will try to inspect what happens .... in other words...if we try to kill an amplifier..then we will discover that, when we try hard to kill ....we really can kill an amplifier.

Some designer uses V/I limiters, an awfull solution that compresses and limits sound...reducing the dinamics...he has some amplifier without this terrible feature...but i imagine that he had introduced forced by the reality...some guys and kill an amplifier and blame the designer...so..... some designers kills the performance to avoid the complaint.

Great guy Mr. Borivoje Jagodic, a very respectable man.

regards,

Carlos
