Labs X600 Power-amp

The
X600 utilizes the same face plate, meter, and front end circuitry
as in the larger X1000. It has a proportionately smaller power
supply and output stage. The output follower stage consists of
48 power Mosfets per channel for a total of over 7200 watts short
term dissipation. The power supply features a single massive toroidal
transformers rated at 4 KVA, and over 180,000 uF of storage capacitance.
Like the meter on the X1000, the X600 meter measures the current
drawn by the output stage. At idle, it sits at half scale, reflecting
the standing bias current of Class A operation. As the amplifier
exceeds its class "A" rating the needle on the amplifier
will register the increased bias being drawn by the output stage.
Also like the X1000, the X600 only accepts balanced inputs.
