Amplifier Cabinet V 3

This image shows the latest thoughts on how the amplifier will look. This has taken ages so the black discs as placeholders for the knobs will have to stay for now – having just learnt Blender (3D image creation and animation) I cannot bear to work on it anymore as I want to carry on with the design of the amp itself – not its mock-up.

I was doing really well with Blender especially since the tools are not Apple standards, this is an application ported from Windows. A very alien environment. So I left it for a couple of days and when I went back to it just now to add the front image I couldn’t remember how to use it! So that means going through all the video tutorials again which took ages the first time I did it.

Amplifier Cabinet Version 3

There is some explanation needed:

The cabinet is painted an off-white gloss colour, something similar to ‘Old English White’. The top of the cabinet is 18mm thick MDF and inset into the lower edge of this (leaving a 3mm white edge) is a solid aluminium bar of 15mm x 3mm. Polished. The same is at the bottom. I do not know Blender well enough to make the MDF or the aluminium look right but this will do. The cabinet is 550mm wide, 106mm high and 382mm deep.

Reading from left top to right bottom:
The amber dot is the indicator lamp (to show when the unit is being charged),
below this is the rotary selector switch, turn anticlockwise to show the battery voltage on the meter and clockwise to charge the batteries, centre off,
the volt meter to show when the battery needs charging,
a 3.5mm stereo jack input (for easy connection of a passing iPod etc),
rotary switch to change the left channel from speaker to headphone,
6 way input selector switch (one 3.5mm jack on the front and 5 pairs of phono inputs on the rear)
gain control with 3 positions (one for listening low e.g. at night, one loud position for parties of general blasting, one for normal listening levels),
right volume control,
rotary switch to change the right channel from speaker to headphone,
3.5mm headphone socket (the small one in other words),
6.35mm headphone socket (the large one in other words).

The layout of the front panel is almost exclusively governed by the components on the circuit board.
