Mission made many models called the 700 . I'm trying to see what model you have so that we may determine the efficiency / sensitivity of your particular speakers , and thereby figure out which valve amp may work . Valve life can be longer if the amplifier is biased cool ( 50 to 70 % of max dissipation ) and placed in well ventilated position ( not in the TV cabinet ) . ;) [/QUOTE]
