the ones that output at close to / at / or above spec
two SP 171's
One I-90 argon
one i-90 ar/kr
Three lexel 95s
coherent sabre
Two lexel 88's but their passbanks both need repair
and the last time i had 480 3 phase the i-300 k3 did power up and put out two watts of red, but of course i dont have 480 in my house to keep running it
Of course there are others that run, i would say 5 of them dont fire at all
