[Hallicrafters] VACUUM TUBE AMPLIFIERS

I have a Krell power AMP that uses 6 Power MOS FET's per channel, in the Output. Electronically
these behave like Vacuum Tubes without the 'pilot lights'.

Pretty hard to beat by any standard, a little heavy at 150lbs weight.

A 1 Ohm speaker output will put out a solid 3200Watts in Bridge mode.

Needs a 20 Amp circuit from the mains.

Some people say I can be excessive, can't see it myself.
