I have (2) L1 II and the the input jacks are becoming loose, intermittent and noisey. The plastic nut on the 1/2 TRS isolating jacks are beginning strip. I am also concerned that the solder connections to the circuit boards below may be becoming suspect on both units. With at least one of the units when intermittent there is a bad 60Hz hum so I am thinking the shield connection may be opening up. Jiggling the input cable at the input jack will generally "fix" it temporarily. The input TRS cabling has been checked with a cable continuity checker and is ok. This does not appear to be easily field repairable. Please advise
