THD Attenuator HOTPLATE 16 ohm specification. I received this from a friend, but as I have no environment to test it, I am selling it as a junk item with the operation unconfirmed. Included items are the main unit, instruction manual, warranty, and box. Please note that this is a junk item, so no claims or returns are accepted. The following is the description: ◆ A passive type attenuator/load box that was all the rage. It can handle continuous 150W, up to about 185W maximum. It is possible to reduce the loud sound of a fully operating vacuum tube amplifier to any volume. Although it needs to be connected to a cabinet (or dummy load), it also has a line out, so it's ready for recording. The Bright/Deep switch is useful in such cases. When -16db attenuation is selected, the right volume (-∞db/0db～-16db) becomes active, allowing for fine adjustments like a master volume. Main Specifications: Max: 185W RMS Attenuate: -0db, -4db, -8db, -12db, -16db (Right; Volume ON), LOAD Controls: Bulbs ON/OFF, Bright SW, Deep SW, LINEOUT Level (Rear) Jacks: INPUT (from AMP), LINE OUT, SPEAKER OUT1&2 Size/Weight: 7.3 x 20.9 x 18.4 (cm) / 1.9kg
