Amplifier: Homebrew:
-Modified Borbely Servo 50 (JFET input, bipolar VAS, MOSFET outputs) biased to 15 W Class A
-Several headphone amplifiers (most are based on opamp driving monolithic or discrete buffers using multiloop feedback, and recently a new design from R.Marsh featured in Linear Audio mag)
Preamplifier (or None if Integrated): All Homebrew:
- sometimes use discrete JFET non-global feedback line driver
- sometimes use discrete JFET unity gain buffer
- sometimes use discrete JFET opamp (like fred forrsell design) with global feedback
- sometimes using AD744+AD811 hybrid
(depending on my mood)
all use either Jung super regulators or emitter followers buffering filtered references
