NEW Class A 50W+50W L10+Power board+speaker protection-LJM
Parameter:
L10 LJM original circuit design, using 2.0 mm FR4 double-sided board based 2OZ copper, 5 foot ring precision 0.5mm copper resistance, small capacitance using all the top class Japanese fever tonic capacitance (Japan Chemical, ruby, NICHICON, etc.), all New Japanese import original 2SA1943 and 2SA5200 Toshiba tube per channel 6 (very good speed and control) to promote the management of 2SC5171 and 2SA1930 audio on the tube, the circuit design is very reasonable, the machine completely current sound, pure sound quality is pure and honest, Excellent sound detail. A sound is warm, the sound quality than the tube amp for 4-12 inch box with a variety of names.
12 with the insulating film distribution board
The amplifier board a channel one, composed of one to two stereo power amplifier, power amplifier to make a finished product but also together with the heat sink and power rectifier board, transformer enclosures, etc.

Full bridge rectified output current +-16A
Original Japanese chemical NCC NIPPON-CHEMICON 50V 6800UF capacitor 4
Using fully shielded sealed relays 10A two.
Protection circuit input voltage AC12V to AC15 single.
Amplifier input voltage is less than AC35-0-AC35V.
With a boot delay, output DC protection off, amplifier power supply overcurrent protection, status indication LED.
State at boot time delay, LED flashes. Detection amplifier without DC normal, the relay is turned on. LED stops flashing.
Maintaining long bright state.
When the amplifier output DC, relay protection, LED flashing reminder.
