Ron, don't go over to the dark side. 5 volts DC with an adequate current supply will toast speakers. Used to have quick release relays on early models, which were also troublesome. I think I have one (not same model or mfgr, but ear accurate) in the basement which I never fired up again. Want me to look? If I find it, yours for half the postage so I never touch it again. Remember I am primarilarily an octalist/vacuumist.
