I have a problem I have not been able to isolate on a system based around a Luxman L-480. Speakers are AR-MST/1’s and AR-6’s. Source is a phone into the L480.
Problem: no output on right channel in either Main or Remote speaker modes.
I’ve isolated the problem to the amp section. There are LED power indicators for the amp section which are activating equally with program material on both sides.
This amp was fully functional as of August but I haven’t used it since then. Both sets of speakers are fully functional. I don’t see any problem with speaker wire and it would be crazy for two different speaker cables to fail at all and simultaneously.
I used to get problems with a dirty Mode switch (stereo, mono, reverse). Normally wiggling it would get rid of any intermittency. No luck this time. I don’t think this is the problem but I cleaned the switch with deoxit anyway. No change.
The amp may have taken some damage. Long story short, I took it to a rental in the woods with me and it got tossed by a bear. I left my passenger door open with the amp in the seat in the woods for too long. A bear came and ended up flipping the amp over onto the center console while rummaging through the car. I didn’t see this happen but there were claw and bite marks on other things in the car, so it’s a safe assumption. The case took no noticeable damage but I haven’t used the amp since this incident.
Any ideas?
