Divided by 13 RSA 31

Refined and voiced closer to our favorite EL84 30 Watt amplifier from England, the RSA 31 offers a little more pronounced midrange and is a little more aggressive than the ERT 33, but still retains a tight, punchy lower end and has half power potential.

Channel One is laid out with Volume, Treble, "Middle", and Bass controls, giving the player the ability to move around the most important "Middle" of this type of amplifier format. And rounding it off, Channel Two remains the now familiar, gainier "Click" Channel powered by a 5879 Pentode with an adjustable frequency range and volume control.

RSA 31s -- Now available in a smaller, one channel version to go with 2x12D cabinet "Small Club Series", or whichever cabinet you prefer.
