Bell Howell Cinema tube amplifiers under Western Electric License. Each uses 6V6 x 3, 5Y3, 12AX7 x 2, and 5879 tubes.

I bought 3 of these. They will be used for tweeters, from 4500Hz and up or crossed over higher, driving JBL 2402 drivers with the bullet horn replaced by a custom walnut mini-Smith Horn.
