A-13 bare board
serial regulator, output + and – 15V, 1A, with rectifier and filter capacitor board size: L 88mm X W 60mm
TP-1 bare board MOSfet High Voltage Regulator, using MOSfet as regulator, using constant current source, B+ can adjust from 100 to 350V 200mA by change the two zener diode. Heater voltage reglator (LM317) selectable from 6.3V and 12.6V board size: L220mm X W62mm
A-19 bare board output voltage adjust from 5V to 20V Max output curennt 5A (use a larger size heatsink) use LT1083 as volatge regulator board size:L110mm W60mm thickness 2.5mm
TP-2 bare board 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-31B assembled & tested Output DC voltage: High 200V × 2 Filament 6.3V × 2 -15V × 1 -24V × 1 board size : 125mm×230mm
