This is the PCBs of a discrete opamp Sun. The design features :

1. Symmetric JFET input ;

2. JFET-BJT cascode output ;

3. high operating current ( 30mA@ +/-15Vdc )

The finished opamp can be used to replace standard single opamp.

The open loop gain is 38dB. It is recommended for amplifier circuit with gain not more than 25dB.

The sound is precise, uncompressed and warm, without the forward and muddy character in most single chip opamp in the market.

The listing is for a set of two pieces of bare boards. The assembled opamp pictures are for reference only.

Specification :

Open loop gain : 38dB.

Operating current : 30mA@+/-15VDC

Operating voltage :+/-12V to +/-25V
