This amp work how sound

 

[Steve Dunlap]

This amp is claimed to be VERY good if you believe reviewers. Considering the price, you may have trouble finding one to listen to in person. I have heard most of the ridiculously priced amps, but not this one. The schematic is simple enough. Build one and try it. I suspect it will sound quite good.

in a similar circuit

i was working with ...in a similar topology R13-14 was the sonic killers but also keep the amp working safelly .....

i could built it too ..... but on the other hand i dont like amps that have no trimers on them ....... there is nothing to adjust on them .... ha ha ha


then again 50 volt rails looks kinda much for only a couple of transistors

what happens in 4 ohms .... can these two transistors handle it ????

i think not .... well lets see ...

another thing i dont recall seeing somewhere else is the diodes in parallel with the base resistors ( D3-D4) ..... can somebody what is the exact purpus of that ????
thanks

The circuit was published by Mr Deletraz without component values. Seems it has now been simulated.

The author of the circuit and the patent does not understand how to use D3 and D4, unfortunately. Read

This amp has serious design flaws (see fuse blow).

Isn't this just a current feedback amplifier with a diamond buffer outside the loop as output stage? No emitter resistors, neiter in the input nor the output stage. I wonder at what bias it runs.

I guess it'll sound like a le Classe A.

 

[bogdan_borko]

Yes this IS a "feedback amplifier".

re

build this...?
and the bias adjust?

nobody has used this schematic ?
