Burning Amplifier BA-2

Two is routinely a little more quiet with regards to mechanical
noise, but has a little more loss in the rectifiers.

What about an F3 front end connected to follower output stage?

Hi cviller,

please, what is the use of the (extra D3) an D4 on your BA-2 Board? They are not mentioned in the circuit.

Is there a BA-x guide similar to F5 and F4?

Hi ZenMod,

I had to google "itching" means "kratzen, jucken" in German, but I don´t understand what you want to say to me?

I already have a bald point on my headby itching the same place, but it does not help, should I continue?

[Zen Mod]

itching fingers , itching head - whatever

meaning is same - too much thinking about building things ...... too little time in listening da muzak .....

are you listening while you're building/thinkin' ?

if yes - then just say to me

oh ZenMod,

I have holidays......

I hear music very often the last days, Mile Davis, John McLaughlin, Yello and many other good things.

I did not change BA-1, the sound is very pleasing.

.....but I want to know what changes when I go back to push-pull!

and the board dimensions of BA-1 and BA-2 are very similar, so change is easy.

All is done without stress I want to keep holiday feeling.....

I hope you are well toooooooooooooo!

The reason for the extra diodes is kinda crazy... we decided that it would be nice to make it possible to cut the boards to 2 or 4 pairs and if you want to preserve symmetry need those extra diodes. Don't worry about them.

Ehh, would the full blown 6 pair BA-2 be ok to drive 1ohm ribbon tweeters ?
I suppose a tweeter will be an easier load ?

Think I anyone can build these to use for car audio?. Thinking single chassis with 8 channels. No idea. Thanks.
