Steve - very nice looking piece of work! I have much the same road ahead of me on my RCA BTA-1MX - which has a pretty similar topology to the Gates - a bunch of 807s driving two pairs of 833s - RF and Audio... It's getting to be so many resuced BC rigs coming operational that we're going to need 'Big Iron' subbands.. hihi! Cheers John KB6SCO DM09fg
