thanks for the input...
hmm,....thats what makes me most nervous, maybe running them at 6amps
is the pain-limit? i currently use jvl drivers 100% flawless hour
after hour, year after year, rated to 6 amps, and i squeeze out all
of those amps, and they dont get hotter than a fart, but they cost 3
times more than the 201´s....
the only reason why i was thinking of a swap to the geckos is that i
thought i could save a some $. however, i dont want to spend my time
travelin around and replace popped g201´s...
does anyone know any commercial, heavy duty, serious machine brand
out there with geckos that runs ok? (at 6 or even 7 amps)
