Default Pictures of my gainclone

well just got a digicam from a friend for the purpose of taking pictures of the gainclone

The "public amplifier" thing on the bottom is the power supply (the knobs/pots do nothing, neither does chime/siren)

They're 3875's.
The circuit I used was peter daniel's inverted circuit. Riken 220k/10k resistors, black gate 4.7uF caps, and Panasonic FC 1000uF caps. The supply (pictures coming tonight) is 400VA, 2x22V secondaries toroid from Plitron (they have a LONG lead time), MUR1520 diodes forming the bridge. And I'm using a 4A fuse, hasn't blown so far, so it is fine.

Binding posts on one are crappy plastic type i pulled off of somewhere, and on the other are un-insulated nickel type .. both crappy
I almost got some wbt ones today, but it ended being $70 after shipping, plus customs so i changed my mind and got LOTS of blue LEDs instead .. 100 to be exact
I'll probably leave some 30 for myself, and offer the rest here for fairly cheap. Something along the lines of $0.50-$0.75 each .. i'll post info of that later

Default You`ve just gotta love this Gainclone nonsense!

Just look at what elizard has produced, and I mean this with the greatest of respect, a chip with a bunch of wires hanging off it, sitting on top of an old PA amplifier case. The really GREAT thing about this (having just built a Gainclone that looks like a plate of spaghetti), is that we know just how good these things sound. I reckon there`s many a manufacturer building and selling amplifiers costing a lot of money that sound no where near as good as a Gainclone

Nice work. It seems like the new trend is bulding GC's into all sorts of old gear.
