HOW THE STEEL IS FORGED INTO A SOUND CRAFT
HOW AN M-AMP IS BUILT
First of all an idea and a schematic is needed upon which the amplifier will be built. The described amplifier will be based around the following schematic and will employ 2A3 and E86C tubes.
Having the schematic, the components that will be used are collected.
They are laid down and the first rough dimension measurements are done.
After designing the chassis with CAD software, a printout is taken and checked to ensure that the components fit.
Now it is time to send to the factory the DWG file to cut and bend the steel chassis.
Next the corners and the bottom rails ( that will support the bottom cover ) are welded and the chassis is brushed and chrome electroplated.
This is the chassis after cutting, bending, welding and electroplating and just before being painted with three layers of electrostatic coating.
Here is the chassis after painting with three layers of electrostatic coating.
This is a detail, under the chassis, depicting non coated areas for grounding and heat dissipation.
Just before the finish.
The 2A3 Amplifier is finished and will undergo some heavy testing.
The amplifier has undergone and passed several tests, including the final one : burning @ 80 % of its rated output power for a continuous 24 hours.
