You lot forget that the case of the Telos 1000 is the heatsink.
~10,000 square centimeters of surface (aka ~600 sq in.)

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,...

Did you match the output MOSFETs?
Despite you don't have the thermal runway since the MOSFET has a positive thermal coefficient, however unmatched MOSFETs connected in parallel may causes current flowing in a particular cell much bigger than the others and that will be a source of distortion. Matching MOSFET is always a problem for DIYer since we can't buy hundreds of the transistor to sort out what we want.
