Other Notes: "The ZH230 is a stereo vacuum-tube amplifier that uses the output transformerless ZOTL technology (US Patent 5,612,646). The ZH230 uses moderately high bias currents in the output tubes compared with some Berning products. This is possible because of the lower power of the amplifier. The ZH230 is designed for loudspeaker loads ranging from 4 Ohms to 16 Ohms, and can be operated without a load. Single-ended RCA type inputs and binding post outputs are provided." - David Berning
