The Mach2 Pre+ PCB is the result of an exciting collaboration with Bancika from DIYfever based on his MKIIC+ PCB project.
All of the features from his design are retained and are as follows.
- 2CH preamp based on the legendary IIC+ as used by James Hetfield & John Petrucci.
- Optional bright and deep switches
- Multiple heater options.
- Regulated B+
In addition to those I have added a spot for a variable EQ slope that can be installed as a trimpot on the board or wired to a chassis mount pot.
This board pairs up extremely well with the Aurora Audio Focal Point GEQ PCB for a more complete IIC+ experience.
Please note this PCB is not for inexperienced users. You are working with high voltages that are potentially fatal.
