RUNOFFGROOVE: Supreaux

This is the Runoff Groove Supreaux, their first interpretation of a Supro 16T amp.  

It's also known as the JHS Superbolt - which is almost identical to the Supreaux, but runs at 18v with a gain switch added.   Just put the schematics side by side, and you will see what I mean.  

I added the 22n input cap, which is missing from the original (it appears on the JHS version).  Swap it for a 100k resistor if you prefer the original - or you could do both.

Like anything using J201s - make sure you buy real ones or prepare for disappointment.  Bias drains to half voltage as a starting point and then tune by ear.
