L20SE Stereo AMP Dual Channel  Amplifier Boards 2SA1943 2SC5200

Parameters:
Power: 350W 4R
Power supply range: DC + -15V DC, to DC + -65V DC.
The recommended DC voltage is +-40V, which is ideal for household use.
It is recommended to use dual 15V to dual 40V transformer 200VA.
THD = (0.001%-0.002% 20HZ-20KHZ) 10W RMS 8 OHM
SR= 35V /US
Noise: 92DBU
EIN=114 DB
Frequency response: 10HZ-25KHZ +-0.02 DB
The voltage gain is 34 times.
The quiescent current of the power tube is about 20MA per tube.

Features:
1. L20 SE simplified version of pure post-amplifier, with excellent and extremely excellent control, ultra-low distortion, wide voltage support range. High-power and high-current output load.
2. Two pairs of TOSHIBA A1943 C5200 per channel, current load maximum 20A.
3. A wide range of voltage support, two pairs per channel, four pairs of high-power tubes can be installed arbitrarily. The standard kit is 2 pairs of high-power tubes per channel.
4. All resistors use precision copper feet 1% high-precision resistors, including high-precision output resistors.
5. All capacitors are imported and original
6. All small signal transistors use original ONSEMI TOSHIA transistors.
7. The push tube and high-power tube use TOSHIBA TTA1943 TTC5200 and Toshiba A1930 C5171 audio dedicated imported original transistors.
8. Two boards in the kit, one board and one channel. L20 must use the original transistors, and do not change other brand models at will.
9. L20SE uses common standard PCB technology, 1.6MM 1 OZ material.
10. L20SE components can be used after being installed against the PCB without any adjustment.
