Numark Matrix 2, CD DJ desk , 2003 ?
 

The central mixer separate.
Anyone happen to know where 2 fibre washers , as used on 1/4 inch jack
sockets, would have come from. They dropped on the bench , unnoticed. I
cannot see 2 being left over at assembly. The 2 sockets I had left in place
so not from there. No obvious place to put them. A fudge due to engineering
fixings alignment problem ?
In for bad output RCA/phono socket but now in there, the soldering elsewhere
is terrible , not PbF probably just not enough solder, ring cracks emerging
on the ps board including a wire jumper joint. Bodes ill for the 2 CD units

sheet metal work cock-up, the rear sub-chassis is 1.5mm shorter than the
front so 2 fibre washers, for padding out, so as not to strain/split the
plastic outer case
