Topology

The CRYSTAL FORTY EIGHT inspired by the DR50/4 of the mid '70s with some major changes.

The power supply is severely overbuilt and totally "Bulletproof" with many additional filtering stages and hand wound, custom built transformers wound directly on a paper bobbin.

The CRYSTAL has a single tone control that is completely by-passable. When turned off it is completely removed from the circuit.
A Line out jack is provided for direct connection to another amplifier,  recording-mixing console or monitor headphone.

"Under The Hood" Lighting  uses two special lamp fixtures that are powered from a separate, dedicated rectifier circuit. Their use has no effect on the heater voltages in the amplifier.  The brightness is controlled by dimmer knob located on the rear of the chassis. You can set the brightness to mildly accentuate the glow of the tubes, or crank it up and make the Hood virtually disappear.   Add $100.00 for this option.  

The Chrome Plated Hood upgrade adds a sleek look to the design of the CRYSTAL Line. Normally, the CRYSTAL comes with a painted hood. Choice of textured finish colors. Add $175.00 for chrome plating.

Folding Chrome Handles furthers the High Class look of the CRYSTAL. Add $75.00 for this option. 

LED Illuminated Toggle Switches When you turn on the power the switch lights up green, and the standby switch lights red. When switching to play, the red turns to green!  Add $50.00 for this option.
