Inspired by the Helios 69 and using the same circuitry but with better (IMO) modern equivalent components such as transistors, capacitors, and output transformers, the HE69MP is a vintage sounding mic preamp and eq with the same filters found on the Helios EQ's as well as a very similar mojo.
Audio enters through a vibrant smooth Jensen input transformer and goes through a recreation of the 2128 amp circuit that is found in Helios modules. The signal can continue through the very effective EQ or can be bypassed right to the 22113 output amp.
We added another small stage to the 22113 so to incorporate a Cinemag output transformer that adds a warm push that jives well with the Helios circuit. It also makes the 1u mic preamp/eq balanced (which unlike the originals which went unbalanced) making it easier to incorporate into the modern studio.
