*** All info is in the DIYaudio thread ***
--Higlights of my version--
* C-multipliers onboard as last power stage
* Heatsinks for output pair & C-multiplier active device
* Both BCE&ECB footprint supported for output pair
* Input JFET pair compatible with both THT&SMD footprint
* THT JFETs can be both SGD&GSD with minimal bending
* SMD JFETs are SOT-23 Fairchild MMBF5457/MMBF5460 pinout
* Input JFET pair, presumed Source & Drain are interchangeable
* SMD JFETs heatsink possible (13x11x11mm H36)
