ZVEX iMPAMP

Interesting product. Wish it wasn’t getting /.ed quite so bad. Would like to see more on the tiny tubes they are using. Also would like to know more on the 12 volt power…

   hi,

   the 12VAC power is supplied by a 1000mA wall wart. it is stepped up inside the iMPAMP to a high voltage for the B+ plate supplies, using two independent linear power supplies for complete isolation between the channels. the 12VAC is also used to feed the tube filaments.

   there’s a video at impamp.com featuring the tubes, and here’s a link for more info about subminiature tubes:
