Roctal 30

This was a custom ordered amp from a creative buyer. He wanted all octal tubes, a pentode channel with Contour switch, a triode channel with TMB tone stack, switchable solid state or tube rectifier, power amp switchable between four 6V6′s or two 6L6′s. All class A cathode bias push pull.  Built with Mercury transformers. Like Burger King, sometimes you can “have it your way”
