PB, PJ and I have been working on a new project for the past couple months. This is our new premium 2A3 monoblock amplifier. It is designed to run a broad range of 2A3 variants up to and including the JJ 2A3-40 by virtue of a two way switchable operating point. The current draw of the 2A3 in a given operating mode is indicated by the meter. It uses a parallel feed output stage and a cap coupled, shunt regulated driver stage. It uses the big OT-5 output transformer that we use in the Kaiju. I'm going to let PB weigh in on the performance specs of various 2A3 tube types, as he is the one who has been playing with them. Sonically it is a little more towards neutral than a Kaiju (a but less lower midrange/upper bass weight) and thus has a little bit more resolved sounding vocals and a wee bit more top end shimmer. That said, with similar circuits and iron both amps are definitely from the same sonic family. Universal power transformer, and a very low noise floor similar to the old Paramount monoblocks. Kit price is estimated at $2250 for the pair of monoblocks. Yes, those shrouds and the black finish are how the production kit will look.
