It’s a popular amplifier with ~40W power and 8ohm
Works on those elements:
- Toroid 250W 2x24V
- double rectify bridge on fast diodes 8xBYW 29E-200
- boards with GC by Krawiec (AS forum)
- 2x LM3875TF
- 4x Panasonic FC 1000uF/50V
- resistors package ELPOD 22ppm 0,5%

casing: high 75mm, wide 260mm, length 200mm
radiators cut on milling machine from 10cm to 7cm
Front aluminum panel 10mm, at inside milled to 3,5mm to allow set elements.
Bakelite top and bottom board 6mm, rear wall also bakelite but 10mm with slots
Toroid with bridge are outside the casing on double vein cable (power) and 4 vain to powered power amps.

Front and radiators are sand painted – front black luster,radiators black lusterless.
Brass ball works with 6mm axle, power button also brass, both painted by colorless lacquer.
Power button 3A inside fasten.
Diode that is responsible for showing amplifier work plug to one power branch through 100k ohm.
Casing put together on ITEM profile 20mm

bananas slots similar to WBT
casing weight ~3kg
Radiators are much too big for that bones so device is tepid even when play very hard.

Sound compare to… yeah to what? … symasym… no compare – two different amplifiers with completely different characteristic, we can say that gainclone is for censers – clear sound without any noise. Symasym is for more dynamic, entertainment.
Of course it’s personal suggestion.
One people love gainclone, other hate it.
System is perfect for beginner user who want to make amplifier, it’s quite cheap and easy to build with “spider” system.
