The new drivers are Rev C boards, designed to use the same mounting holes as the ATU. Which explains the unusual shape. We also removed all of the extraneous components needed for stand-alone operation as we will be introducing a new stand-alone amp soon.

Virtually everything is pre-installed SMT, leaving only the terminal blocks, power cable and MOSFET for the builder to solder.

I'm testing one on the bench today (11/16/17) and it puts out a solid 5W with <0.5W input, harmonics < -25 dBc, not useful on the air without a filter but plenty clean-enough to drive the HR50.

The only issue is the IN and OU labels are reversed, we'll put a sticker on it.
