It has a sliding bias. It operated as a pure class A amplfier up to a given power then its bias changes to a class A/B operation. It is a high current amplfier capable of stereo 1 ohm loads.

25 watts minimum pure class A @ up to 180 degrees heatsink temp. Below 115 degrees it does about 45 watts pure class A.This is a function of thermal derating of the output devices.

Told ya!

Looks like it needs to be modified with a watercooling system

 

[NOFATTYS]

excuse my ignorance...but what does pure class a mean exactly compared to a/b?

How much amps did it pull at idle?

How much amps did it pull at idle?

quite a bit, i was told 20-25 amps, never measured it.
it gets fairly toasty to the touch after its on for 10-15 min.
