r-amplifiers/l12 -2-a-really-good-100w-amplifier/
Size: 360mm*270mm*80mm (W*D*H)
Output Power 120W+120W (at 8ohm load) 200W +200W ( at 4ohm load) LJM design rigorously tested high performance amplifier. Using asymmetric amplification, cascode input, single-ended constant current amplification, complementary feedback output stage.Static current per channel is 40MA working at CLASS AB.
L12-2 Since 2006, the number of users has exceeded thousands, which reflects very good, is the classic model in the L series.
PCB uses double-sided 2MM thick FR4 material. Small signal tube using original TOSHIBA low noise tube The output Transistor adopts the original Sanken UHF FT 70M, multi-emitter LAPT audio Transistor.
2SA1186 2SC2837, two pairs of output tubes per channel
300W oxygen-free copper transformer
4X10000uf NOVER Main filter capacitors.
original ALPS volume Potentiometer.
Aluminum chassis + solid knob
High Quality Speaker and RCA Terminals
The main material: THD<0.0005% 1K HZ 10W SR = 35V/US Damping factor >200, 8ohm load Input sensitivity = 1.6V output 120W 8R Frequency response range = 15HZ-50K HZ (-3DB) 20HZ* 20K HZ =-0.02 DB Static current = 80MA Voltage usage range = DC positive and negative dual voltage + -12V to + -55V Voltage magnification = 31 times
