Hybrid valve and TPA311x
« on: November 15, 2018, 07:52:42 PM »
Two years have tested others and this one sounds the best.
 I built it point to point but now doing a board.
The tone tilt I think beats all others. Shown here in hifi mode but easy to add scoop.
Uses 12AU7 and $3.00 D class module.

Schematic attached. The fx loop is not fully tested.
