I make this amplifier according to the schematic of the Goldmund Telos
5000 amplifier
I try not changed much compared to the original design
Some positions do not find the original design of components, I
replaced the equivalent.

This is

1. Power Diode STTH 6102 = STTH 6002
2. Mosfet: 10N20 = 2SK2221
10P20 = 2SJ352
3. CCS: ADR445BRZ (5V + /-2mV) = AD586 (5V + /-2mV)

4. Not DAC, DAC original design
5. Stereo, the original design is BTL Monoblock
6. Volume relay 5 steps original design control by remote, I used
ALPS 27 - not remote,not CPU,...
