Product Description
Introduction:
HOOD JLH2003 series following JLH1969 after an upgrade version, by the JLH1969 single power supply to OCL dual power supply, and increase the parallel connection, the maximum output power of 22W (8 ohm load) Compared to JLH1969 single power supply, JLH2003 output frequency response curve more straight (due to no output coupling capacitance and affect the frequency response curve).

The circuit magnification is 13 times, suitable for the production of power amplifiers, headphone amplifiers.

For the best sound quality, each tube set the quiescent current of 1A, that is, the emitter cement resistance (0.2R) at both ends of the voltage difference of 100mV.

Warm Tip: 22W pure class A power amplifier, heat is relatively large, before connecting the power supply, please pay attention to increase the large radiator cooling. (Photo angle aluminum is only used to connect a large radiator).

PCB size: 156 * 75mm
Angle aluminum Size: 35*35mm*3mm  (Length 156mm)
Input voltage, DC +/-18V  (Please use AC 13V--0--13V 200W (Each channel) transformer + Rectifier power board)
Output power: Class A 22W +22W (8ohm load)
NOTE: We have PCB or DIY kit or Finished board (Optional)   ◆ PCB ---- Bare board PCB without any parts.   ◆ DIY kit ---- All parts need you to solder and test it.   ◆ Finished board ---- All parts have been welded and tested OK.
