And don't confuse the original Herc 444 with the Herc II (420). The 420 
IS repairable.  The 444 was discontinued soon after it was introduced 
because Motorola discontinued the output devices. Cost Ten Tec a lot of 
money. The Herc 444 was a very nice amp (I had one for a while), very 
well protected. The only flaw I know of was a thermal voltage regulation 
problem in the power supply that, because of Motorola's move, never got 
fixed (apparently they didn't want to spend engineering time to fix a 
design that was dead).
