Falsely claims to be Pass ACA but differs in the following: Q1 and Q2 should be IRFP240 not the supplied IRFP250 even though the silkscreen itself reads IRFP240; Q3 should be ZTX450 not BC550C; Q4 should be 2SK170 not K30A. Missing the 10uF capacitor C4 Should be supplied with LED diode, not FR207 For part number reference compare to Nelson Pass ACA schematic. Gave two stars since the board quality is excellent.
Can't argue with great sound! Amp is up and running and is fantastic! Seller has responded that they substituted some of the transistors with comparable or better ones and data sheets suggest this is reasonable. FIVE STARS!
