Item description

This is the PCB of a discrete opamp amplifier. The design is an extract from the one of the amplifier circuits being used in Marantz PM series. The design features differential input and single-ended class A output. The supply voltage is good to +/-32V which means a lot of headroom comparing to normally +/-15V opamp circuits. When matches with a decent DC power supply, the circuit can beat off-the-shelf die-size opamp with ease. This board can be used as building block for preamplifiers, active filters and the gain stage of power amplifiers. Each board consists of two individual amplifiers ( separated ground and power lines). PCB dimension: 66mm x 106mm. PCB thickness 1.6mm. Super thick copper ( 2oz) is used, which is three times the normal thickness. We provide detail schematic and part list to buyers by EMAIL. We do air shipping worldwide at US$4.00. We welcome combine shipping. Track Page Views With Auctiva's FREE Counter On Mar-05-09 at 01:27:39 PST, seller added the following information: Sellers: Get your own map today. Click here now.
