VRM is our "Voltage Regulation Module" kit based on the VVR design but modified to minimize voltage drop. Technically it is simply a variable B+ voltage control.
It is designed to reduce the power level of your amp while retaining the sound. Essentially, you get very close to the same sound at a lower volume. The tiny board size means silent operation and should fit anywhere in your Trinity Amp.
Specs:
Board size approx 1.25" sq.
B+ Voltage drop 2.7V @ 100 ma
Current limited at 230ma
7A MOSFET device mounted on PCB or remote
Simple connections required - B+ line in, B+ line out, ground.
Replace the power switch in your amp with the "switched" control pot VRM kit for $40 plus $8 shipping in North America and $15 shipped elsewhere. . Kit include all parts: PCB, 1M switched control pot/knob and 2 DC blocking caps to be used on the first tube grids. Make a few connections and you're ready to go.
