I will send you a new board:

Still the LM3875?
Still NI?
Still those widely separated PSU caps?
Still no buffer?
Still unregulated PSU?

Nothing new then...
I think I'll scavenge your amp and put my own stuff inside.
Thanks for the attention, anyway.

Gotta go, this site is too slooooow now, and time to go to bed here.

As my friend says, you don't touch a proven design.

Hi,

As my friend says, you don't touch a proven design.

Especially when there's no design to touch in the first place...

Cheers,

And how do you know that?

LM chip, nothing to design there.
NI or I, nothing to design either.
Widely seperated PSU caps, now that's DESIGN, right?
no buffer? no buffer.
Unregulated PSU? Designed that part? Congratulations.

As my friend says, you don't touch a proven design.

So, your friend must be a very wise man...he knew right away there was no design to change.

Now if someone feels like doing something more challenging, how about designing one of these:

But all those are design choices, wouldn't you agree?

Maybe my friend is not very wise man, but at least my design choices don't bother him as much as they bother you.

Why not?

Hi,

but at least my design choices don't bother him as much as they bother you.

From what I recall your "design choice" was to go for the IGC....
After testing the field that turned out to be a bad "design choice" and 20 or so amplifiers were called back to turn them into NIGC amps.

How many of these "design choices" were there to make?

Thank god it wasn't two dozen of them...

Of course it doesn't bother me that someone claims for about a year or so that IGC is the way to "design" with GCs...
Nah, surely no one's fallen into that mousetrap....

Cheers,
