LM317/337 dual rail regulator kit for preamplifier/headphone amp (red) !

On list is a dual rail regulator kit to be used with low current application ( below 300mA). using LM317, LM337. This board is particular useful for preamplifier or headphone amplifier.

The broad includes protection diodes to protect the regulator chips from high output voltage reversal.

The board features high quality components such as 1% metal film resistors, Elna filtering capacitors and Philips film capacitors.

Voltage input : 12VACx2 to 22VACx2 ( for +/-12V DC to +/-22V DC application).
