Measures were realised through a test-set consisting of Rohde & Schwarz UPD audio analyser, HP 6453A power supply
(200A continuous) and 14F capacitive booster made with audison cable Superfarad capacitors.
Please always choose a fuse of equal or slightly higher value (max 10%) than indicated.
Note:
The use of MAC2 cooling system is strongly recommended when the amplifier is employed at full power with 1 Ohm stereo
or 2 Ohm bridged loads.
