Death of Gain Clone

[ontoaba]

Here an inspiration for a solution for an enclosure/cabinet
Synergy - LM3875 Gainclone Amplifier (Chip Amp)

Why in DIY project GC case replaced with that "baking pan" ???

Why in DIY project GC case replaced with that "baking pan" ???

Not regarded to a technical reason - only regarded the design (the pic looks nice).

Because I received a lot of PMs regarding this project...
Due to the engagement with my work (yes, the money is not
a good thing, but still works when you need to buy some stuff),
I don't have enough time to spend it with my hobbies. The other
reason is that I already moved to the vacuum team. It is simpler
and long time short circuit at the output is not a big deal at all
Attached is the schematic of DoGC with some little improvements.
Will try to test the offset stability at different ambient temps and
will report the results here ASAP. Thank you!

P.S. Still have some PC boards for this project, PM or mail me if you
have any interest or questions: widowmaker@mail.bg

If someone is going away from a Gainclone, why would they pick this particular circuit, there might be better yet simpler circuits out there that outperform Gainclones and this circuit as well..

@metal
I think you are a little too much questioning this circuit.
It has several interesting parts.
And my opinion it is rather simple.

We can not make too simple if we want a good amplifier.
If we do that we run into troubles and sound will not be good.

@widowmaker
Thanks for sharing this circuit once more.
It might bring me back to diyadio.com ....
I have been away for so many years.

Where have you been lineup?
Great to have you back.

 

[AKSA]

Yes, Lineup, I have missed you.....
You are a great asset to this forum and a good friend to me and many others.

Thanks AKSA. And adason.
I am troubled with whathas happend to planet10.
But I see he has recovered pretty well.

I see you AKSA are contributing as you always do.
Even with interesting new designs.

Have a good day, both of you.

Open-loop gain decreases proportionally to frequency. Amplitude of sensed error increases proportionally to frequency. And it uses an interesting mixture of parts.

Long life to Death of Gain Clone!
