    Mark Levinson № 534

    The dual mono amplifier No. 534 contains 12 discrete bipolar output transistors TO-264 15 A, 260 V, 200 W per channel (24 in total); and 12 discrete bipolar transistors TO-220 230 V, 70 MHz per channel (one for each output transistor, 24 in total). Its power supply contains eight discrete high-speed TO-220 Schottky rectifier diodes of 40 A, 250 V per channel (16 in total) and 18 filter capacitors per channel (36 in total), which eventually gives a capacity of 118,800 UF.
