A-11P bare board
TP-2 assembled & tested MOSFET power regulator board, same as TP-1 but constant current source using resistor instead of MosFet, Voltage adjust from 100V~350V by changing two zener diode, current output 200mA. Heater voltage selectable from 6.3V and 12.6V. board size: 220mm X 62mm
GA-19 assembled and tested board two channel voltage regulator on board max input voltage not greater than 75V AC each channel output voltage adjust from 5V to 90V each channel max output current 80mA with current limit protection board size: L120mm W90mm thickness 2.5mm
A-08 bare board Shunt regulator, adjustable from 4V to 40V ,current from 125~250mA, specially for replace the orignal power supply of CD player, pre-amp, DAC LM317 as current limit. Using K703 as the loading device to reduce the output impedance, have short circuit protection board size: L 80mm X W 72mm
