The controversy

[Peter Daniel]

I just received this link from AA :

regarding a controversy with my amp resembling GainCard or as some saying, making a fake GainCard.

Its like saying Jesse James copied Arlen Ness, if you are into custom motorcycles.

Both use the basic Harley (or S&S) motor (National's LM3875). Both use solid tail frames that might appear the same (similar cosmetics). Both are taylored to appeal to different buyers who appreciate the *differences* (different circuit topologies) and are willing to vote with thier ears and dollars.

Thanks for giving everyone another choice, Peter! You're the Gainclone Jesse James (but without the tattoos).

I want to know more about the Ed Sawyer guy, who claims to have compared the gaincard to the amp-1.

Peter asked him where he heard it, unless he knows Srajan I guess there are not a lot of amp-1's out there to hear.

According to his "review", the gaincard was better, but it did not say why. It sounded like he would have liked the gaincard better no matter what, from the tone of his review.

Surely there are only so many shapes that you can practically make an amp casing and the Gaincard wasn't the first with the 'dual mono' look anyway.

All I can say Peter, is it is lucky that you didn't copy 'my' design of casing for your PSU Then again somebody would compare that to the M-F X series cases

Now I could put a list up here of genuine things to complain about if these people have really got nothing better to do but none of them concern the GC in any shape or form.

Peter you had best expect this kind of flack.Even i have sold some clones locally as everyone that hears my GC/Fe-103e horn combo wants a set.
The basic circuit(being discussed here)i was using 15 years ago on a LM741 op amp for amplification of an ir signal and the circuit has been around for a long long time.
You took an idea and went 1 step ahead ,nothing wrong with that.Sure the case is based on the same design principal but so is just about everything sold on the marketplace.

Any stagnent design will be replaced given time.(me)

Also, prepare some good seats and fresh drinks for unsolicited taks men...
Don’t have to tell you what people do for money…and envy.
Anyway, I whish you all the best. Beautiful project!!

well, you took their schematic, slightly modified it, improved it, and put it in a very VERY similar enclosure, what do you expect? its as close as it can be without being the same.

you took their schematic

a joke?

i claim copyright on the schematic below and all circuits that can be derivated from it ....

[apassgear]

That has happen to me before in other comercial endeabours, it souldn't bother since they will always through stones to the new small entrepenours.

It also means that your making waves and people are talking about the product. It would be bad news if you go unnoticed.

For the record, I don't even know what their schematic looks like.

I took Thorsten's schematic and modified it. But, since it is IC chip implementation, anybody could actually do the same.

The parts choice I'm using is proprietary and that creates my design.

I know that the case design is questionable, and I am not surprised by that. I knew it from the beginning. The question is : will it stand it's own in a marketplace?
