Bloodshot Overdrive Biasing

[Fingolfen]

Looking at the Bloodshot Overdrive, we've got two 10K trimmers presumably for biasing the transistors, should this be done by ear, or are there recommended voltages (and what's the quick and dirty way to measure them)?

Anyone? Beuhler?

Usually 4.5v for the 5089 collector and 5v ish for the 5457 drain

FETs aren't always consistent so start with the drain at 5v and see how you like it

Measure the collector and drain pins referenced to ground start with the trimmer halfway and adjust as required
