NAP 200 Quarantine Clone Amplifier

Somewhere in 2015 I went to an audio fair and was lucky to listen to an NAP 200 from NAIM. What a sound! Designed by Naim Audio founder Julian Vereker in 1971, the NAP 200 has established for NAIM quite an legacy. Its design is simple and uncompromising.

Tip: many sellers mention the MPSA18 as (matched) current source transistors. These have IMHO far too much gain/HFE/beta, causing instability, oscillation and noise. My advise is to put the MPSA06 (originally the BC239C was used, but is nowadays hard to find) instead of MPSA18 (total 4 transistors per channel).
