Product Detail

(--- ayanhu81 ebay shop welcome you to buy it ---)

Tips: The board has two colors, blue and green, we were shipped random.

This is an assembled tube amplifier power supply board for the high voltage section.

The board consists of a China 6H6P duodiode ( equivalent to Russia 6X6C) and two 1N4007 silicon diodes forming bridge rectification circuit. Due to the tube's slow ramp up nature, the output ramps up slowly too so as to protect the amplifier circuit during power on.

The filtering section is formed of CLCLC in pi configuration to minimize ripple current. Two sealed oil-based choke coils are used in the circuit. (--- ayanhu81 ebay shop welcome you to buy it ---)

The line ripple coefficient is extremely small, ideal for very immediate effect. Ideal for two tube preamp use.

Input voltage: 0 - 300VAC, 5VAC( for the diode filament)

Output voltage: 0 - 400VDC 20mA
