3) Front Control Panels - Glass Cutting, Silk-screening
One of the hallmark of McIntosh equipments are their front glass panel. The multistage process of making the front glass panels are extremely labor intensive.
Some models use glass panels as thick as 1/2 inch, and a special
glass cutting machine utilizing a high pressure water jet is employed in the process.

An
actual demonstration of a 60,000 PSI water jet cutting a 1/2 thick piece of
glass.
It can cut holes of any shape or size.
The speed at which the machine shoots out water, is faster than the speed of
sound.
If allowed to shoot freely, it will shoot cross 7 football field in less than 2
seconds.

After the water jet shoots through the glass panel, it is cushioned by a heavy
duty steel panel placed under 3 feet of water,
This is what the water jet does to the thick piece of steel panel

Nothing comes out of McIntosh without being thoroughly inspected, over and over
again. Here, we have a technician inspecting a control panel.
Notice this front panel belongs to a much older model. |
So you want a front panel for your Marantz 7 ?
Sorry
.you cant get them cause they don't make em no more.
But if you want a panel for your 1968 Mac C26 Preamp ? McIntosh can still make
them for you.
