hello, ... xl7 user for 2 years, have kids, fly frequently = busted gear! thank you e-mu for being so straightforward in your component layout - i literally know nothing about electronics but I can fix one of these!!!!!!! bad call for using what is considered in electronic component shops in barcelona as " antique parts"!!!!!! ok i'll explain... Watch out when you have to fly with this machine in the baggage hold: precautionary measures of base level consist of this: be sure to take off the plastic knob covering the volume pot to ensure that the nut is still relatively tight before flying anywhere in the world . - failure to do so will result in the volume dial circuit breaking thus leaving your machine with little or no sound across the 6 outputs!!!! thats what just happened to me.* also I hasten to add that the exact piece for the volume dial is very very difficult to get hold of ( at least in spain).. so here's what we did:1. open the machine from behind. 2. undo all the nuts surrounding the headphone jack and the volume dial. 3.a 10 kilo ohm variable resistor pot will do just fine regardless of the length 5 file it down) but be sure to find one of the right width; you 'over the atlantic ' types will find this in " radio shack", germans among you should go to " conrad" knowwhat i mean? chances are that the 3 solderable pins won't fit into the holes on the breadboard - attach wires and connect those instead - makes it easier to repair if ever this happens again. reconnect everything and put the machine back together. apply a tiny drop of exopy hardener to the nut of th volume dial where it touches the outer cover of the machine, this will give it airplane baggage hold proof protection. hope that helps anyone in similar position before sending their machines away and wasting weeks without them. 51m0n
