I got bored about a week or so ago, so started working on this layout. Its a Millett Hybrid, with built in diamond buffers, but added a position so a resistor could be put in series with the gate of a mosfet, so that could be used for the output transistor instead of a BJT. Also have a muting circuit, based off AMB's e12 circuit, and a LM317 regulator. Its sized for the 6" long Lansing Micropak DT1 case. I will post the schematic later, once I get it organized better. I will look into getting one or two made up later this week.

use the tube heaters to bias the mosfets!

unfortunately this requires major jumpering, or mandatory superior output devices
