I often get asked what the core circuit of the vmp series preamps is based on ….
My answer is almost always the same.

The 12AT7 dual triode is employed with every db of gain in its operating range effectively utilized.The first voltage gain block has variable negative feedback adjusted via the pad switch.This also changes the impedance around the circuit to create extra flavours and textures for increased versatility.
Filaments are D.C for quietest operation.
Rails are well beyond your average requirements.
All completely discreet Class ass A technology.
Direct coupling where appropriate for improved transient response.
Propellants are Liquid Oxygen and Liquid Hydrogen.

FOR A SOUND THAT’S BIG AND STRONG
IT HAS TO BE Sebatron …… 8) 8-)
