Default What is a Gain Clone exactly?

What is the history of the GainClone?

Who 'invented' it, who invented the name, who is selling parts and PCB's for it?

Is any amplifier with a LM3875 chip to be called a Gain Clone? Or is there an official recipee?

What is considered to be it's prime qualities apart from low price?

Try this thread first Gainclone and Lab 47 - Peter Daniel?

and then some other threads in Chip Amps forum. This is a pretty good SS amp and properly implemented, might provide quite a competition to your current designs

Are you interested exclusively to buy all the parts at one place?

You shouldn't be an expert to build it.

Default and you have

and you have at least 8 options to build this thingy

I have right now a design for a non inverted, inverted, semi ultimate, pen ultimate, ultimate, a 3875, a 1875, a 3876 etc etc and then I have variation on each theme. ?????? with coupling caps, without, with carbon film resistors, with metal... , if you look at it, it is so incredibly confusing that one could give up before even getting the parts.

I kept with one design, and did not change anything after having ordered parts.

Thanks Peter.

What would be the estimated cost for a DIY'er to build a GC?

I understand that PCB's are not usual for the GC....

I've been constantly playing with those amps for almost a year. While my first amp had about 65% of performance capability, I think I won't be far from truth if I say that the current design provides at least 85% of performance. Just yesterday I tested it against a custom built Aleph 2 and I can say it's a fair match (in some areas actually superior to class A amp)

Although the amp seems to be simple (only 7 parts involved in my setup) it is not that easy to make a top performer out of it.

We are attending this years CES in Vegas (although US custom restrictions prevent me from being there)

The biggest cost is transformer, but even using exotic components the total cost shouldn't exceed $150 (not including chassis.

Check this thread for inspiration in chassis building Trying to improve on a GainCard concept

I don't remeber Jocko's being ever excited about Gainclones.

I've been seeing the name 'GainClone' for a year on a forum, before deciding to investigate the matter more seriously.

AFAIK you are right about this, Jocko wasn’t excited about GCs. But Jocko was, just as me, excited about some kind of question.
