2A3 Push Pull Mono-Blocks

Where D.H.T. combines the beauty of power.

2019 : Our original 2A3GT Push Pull monos are pushing 10 years old, and aging more gracefully than we had ever imagined. However, we haven’t been sitting around sipping espresso lattés and admiring our handiwork this past decade! Instead we’ve been rethinking everything, as usual. How do we improve a design that already ranks among the best (Glad you asked)? Anyway, for the whole new Second Generation:

·         Introduction of the 6SL7 driver tube, addressing customer requests for a more accessible / quieter tube than the good old 6SN7.

·         A new and improved Double Push-Pull driver stage that can adapt either 6SL7 or 6SN7 in either position — interchangeable for those who love tube-rolling. And you can still use two 6SN7 if you got some quiet bad-boys.

·         A better rerouted, spaced, cooling PCB layout with revised grounding scheme.

.         A quieter amplifier with better signal-to-noise measurements and a lowered noise floor.

.         Rationalized parts and transformers
