Top shelf tube gear has never sounded so good and been so reliable.  Tristan has redesigned a classic and made it a price that’s hard to pass up.

Two channels of Passive and Inductor based Program Equalization!
Heavily modified version of the Pultec EQP-1, adding much more flexibility in the Low-End Boost/Cut, and in the High-Cut sections, with excellent Sowter inductors used in the High-Boost.

Single tube design, using one NOS Tesla/Sabre 6DJ8 per channel.
Hammond Transformers isolating both Inputs and Outputs.
