Build yourself a £2000 amp for £100 (Gainclone)

So what is it I'm talking about. Well a Gainclone which is a clone of the 47Labs Gaincard
Philosophy here http://www.sakurasystems.com/products/47amp.html
Review here http://www.tnt-audio.com/ampli/47gaincard2_e.html

So how do you do it. Well all I can say is visit http://www.diyaudio.com/forums/forumdisplay.php?forumid=40 or http://ampchipdiy.com/phpBB2/viewforum.php?f=2 and start reading. Or better still follow the instructions here http://www.decdun.fsnet.co.uk/gainclone.html (although I used a different schematic)

What I can tell you is that it is a 50 watts stereo amp for peanuts which is better than a Rotel RA-01 and as good as my Quad 99.

I have to admit I cheated. I bought the basic circuit from another guy and then made my own changes. I plan on putting it into a plant pot soon and wire in a volume control. Honest!

 

Oh yeah, some pictures

 

The only wire I have in the signal path is from the output to a muting switch. If I eliminated that I could use only the lead out's of the components.

 

Nice picks and build Lee good to see the use of the soldering Iron not dying out. t.

 

Gee

Works OK as well. No good on Apogee, but fine with my Harbeths. I may do another 2 and parallel them to get more welly.

The box is ugly but really useful, and with 4 x 10,000 uF caps in it I could run the LCAudio digital modules...very tempting.

 

You can do a little better for less, if you want too PM me if you wish to go that route. T.

 

Nice bit of 3D circuit design ...who needs PCBs?

Michael.

 

point to point is the way

 

Well it is recommended that the components are as close to the chip as possible

 

OMG, those are the same el caps MF use...I bet it sound smoooooth and dull

only kidding
