Please note that the era of $10 receivers/amps/speakers has passed at least in my area (Albany, NY). It's not impossible, but it takes a LOT of work and more than a little luck. There are some bargains on tuners/cassette decks/open reels/cd and dvd players because they are 'technologically obsolete'. However, I must admit that my last real bargain was Yamaha RX-396 receiver for $15 that was cosmetically challenged.A ten dollar amplifier? If it were mine I'd say go ahead and run the test. I suspect it will pass whatever you throw at it. But it's not mine, so I understand.
P.S. Mr. Hardy is also a regular on Audiokarma as am I.
