THE KLYSTRON BASS MAGNIFIER DESIGN PHILOSOPHY

This is a NO COMPROMISE design using the best parts available wherever possible.
Some examples of this are as follows:-

• Gold plated jack sockets for reliability and long life.

• Full Metal XLR sockets for strength and their positive latching facility.

• All MOSFET output devices for reliability and superior bass power.

• Doubling up of the reservoir capacitors for the output stage providing double the available

‘Punch’ or instantaneous transient power ( very important for bass ).

• Doubling up of the cooling fans for reliability and reduced fan noise ( 2 fans can run at half

the speed to provide the same cooling capacity and as a consequence generate only half the
noise of one fan running at twice the speed).

• Speed controlled fan drive circuit. Again this reduces the amount of fan noise as the fans run

slow when the unit is cool and increase in speed with output power demands.

• Powerful TOROIDAL mains transformer.This is more expensive than a laminated stack

transformer but has better regulation i.e. provides more power on demand without sagging
out and also has a minimal external magnetic field which means that single coil pick up
basses are less likely to pick up mains hum from the amplifier.

• FET input circuit to the preamp for ‘Warmth’ even when using the CLEAN input mix setting.

• D.C. heaters for the TUBE section for low noise operation.

• Switch on delay for silent power up.

• Thermal trip for output protection.

• Relay switched speaker output lines for silent power down.

• Sub Bass output and Sub Harmonics facility for really serious bottom end.

• Plywood Cabinets and Head Sleeves, screwed (not pinned).

• Metal Corners and bar handles.

• Acoustically transparent Custom Grill Cloth.

• Air Sealed speaker cabinet back plates.

• 16swg (1.5mm) zinc coated heavy duty metalwork.

Everything possible has been done to make this a reliable, top of the range, minimum service, high
quality, long lasting powerful bass amplifier.

We know you will appreciate the effort that has been put into the design and manufacture of this
unit and you will be rewarded in your choice of bass amplifier by long life and reliability.
