Like its predecessors, the 610T monoblock is based upon a push-pull, fully balanced vacuum-tube circuit using 6550C output tubes (16 in all). Unlike the earlier models, the 610T uses two 6550C driver tubes, each controlling a bank of eight output tubes operating in unison. Input gain is provided by two 6N1P dual triodes and a 6H30 follower. This means fewer tubes to replace, and a much simpler biasing system: two bias adjustments instead of the 16 required in the REF600 series. Power output is rated at 600+ watts into 4, 8 or 16-ohm loads.
