Default Alternate use for an LM3886 - PSRR/LineReg test set


I just completed my latest piece of test gear. A test set for measuring PSRR or line regulation of a power supply. It'll source/sink several amps with a compliance of up to +/-40 V. It has an AC coupled modulation input as well as an AC coupled output monitor output. It's based on an LM3886...

It can also be used as a stereo power amp...

The BNC connectors are 5/8" (16 mm) apart. That's a bit tight. The standard spacing of 3/4" (19 mm) is much preferred. It works, though.
