THIS IS AN OLD STOCK ITEM - IT HAS BEEN TESTED AND IS IN PERFECT WORKING ORDER.
Give your signals a bit more oomph.
This is a simple op-amp gain module - simple, yet surprisingly useful. As supplied it will provide a gain of up to 10x although this can be altered by changing a single (surface mount) resistor on the PCB. The level of gain is provided via an illuminated Alpha slide potentiometer (funky, eh?)
Since the only active components are an op-amp and an LED, the current draw is surprisingly low - figure on less than 10mA on both rails, even accounting for the LED. Better still, it fits inside 2HP.
Supplied with a laser-cut and engraved panel, mounting hardware and a power cable are also provided.
