?  ... incredible, Phil.  The designer of the AL-1500, Charles Thomas
Rauch, Jun. claimed to be one of our recognized amplifier ''experts''
(9-94, QST) -- yet he has no training in physics, physics of electricity,
or algebra.  The AL-1500 is the only 8877 amplifier that has no vhf
suppressor whatsoever.  .

Is either side of the heater operated at ground potential?.
thanks
cheers, Phil

No Sir, it is wired just like you describe above....
cheers, Rich
