The service manual lists four partnumbers (or better for colours, as the 
trannies were marked with a colour dot) for the VCA transistors, and it 
says "use one color in a unit". I did not have a look at my JX3Ps, but I 
assume 'unit' means 'in each VCA'. There is no common adjustment for all 
VCAs, so it doesn't make sense to have all 6 VCAs made from the same 
match pattern.
