- The Legend of The Stingray -

It all began at the HI-FI ‘97 show. We find the protagonists of this tale seated comfortably at the bar,

of course - J. Gordon Holt with his traditional martini, and EveAnna Manley with her stimulant of choice,

a cup of coffee. She was describing a new integrated amplifier she wanted to build, and proceeded to

make one of those legendary “bar-napkin drawings”. Gordon remarked, “It looks like a stingray [the fish,

not the car]...” and thus, in honor of Gordon, we called this little jobbie “The Stingray”.

Now, in 2008, we have revisited that time-tested design and made a few improvements. As a com-

pany building predominently vacuum-tube equipment, we are never one to be behind the times. Thank

you for supporting Manley Laboratories, and we truly hope the Stingray II brings you as much enjoyment

as possible. Thanks again.
