I have been searching all over the internet for some internal pictures of the original GainCard Model 4706, I have not succeded. Does such pictures exist? Also what is the DC voltage provided by the 170VA toroid transformer, before reticifation?
In short I haven't succeded in finding much detailed info on the original GainCard at all, hope you can help me... |

for the alleged gaincard interior shots, go here and scroll to the bottom, "Some Interesting Photos"
http://home.ca.inter.net/~cfraser/Gainbuilder.htm rjm did a tidy colour drawing over here http://www.geocities.com/rjm003.geo/...io/diy_gc.html compare with the Shigaraki interior shots http://www.hifi.nl/recensies.php?id=1966 there are not yet any pictures of the inside of the humpty. a gc builder has one, and hopes to supply photos later on when he is not enjoying it in his system. a caution: the interior details, and the validity of these gaincard interior shots, have been discussed to death, and with some unfortunate animosity. so people are a little tired of discussing it. this should not be taken personally. |

Do you really think the PCBs from a professional amplifier would be so ugly? They should at least be professionally made, not look homemade.

dezzz, you are not alone in wondering of real picture proofs. Can't anyone dig up a photo where you actually can see the case also? I'll gather that the case is rather hard to open.

If I made amplifiers of that build quality costing many, many $$$, I'd make the difficult to open too! The link ofb posted showing the Shigaraki laid bare proves to me that the pictures of the Gaincard are genuine. The construction quality, component choice and PCB design are too similar to ignore. Regards, David. |

I find it hard to believe that something so expensive could look like a failed school project.
Anyway, why are so many people so enthusiastic about copying something that no one seems to have actually seen?

because it sounds pretty good?
![]() because it's easy to build? because you get a whole lotta bang for buck? here's a link for a review of the gaincard's little brother, shigaraki or something, with pictures of the outside & inside. link looks like it has a similar type of "pcb"...

The same is true for any ordinary chip amplifier. I can't see anything really special about the GainCard that gives it any particular advantage over a normal design (and given the apparent build quality I would say it is probably worse than most amatuer chip amps). I can see an awful lot of horrible market-speak and nothing else.

incidently dezzz, the humpty does not use a toroid. the only description we have is of a cut-core. there was a side-thread of thought that it was an r-core, but cut-core seems to be a better match.
what i can't remember is if the secondary voltage is actually stated anywhere. possibly someone here will remember (not make up or hypothesize or give opinions on why it doesn't matter that you know) and save quite a bit of digging. maybe in another dozen posts or so. |
