Hi. This is my first Luxman, i buy to use in garden for the summer, but i have problem. Right channel work fine, but left channel have very bad sound.
There is no shcematic for my amp, but service manual for Luxman L-1/A is 100% same.
I check bias adjustment /is 50ma on both channel/
I try every inputs (+monitor 1/2) same situation.
I clean all potentiometers with contact cleaner.
Check all capacitors with esr meter - fine.
Check voltages on both chanells - they are same.
Resolder all pots, check all wires in amp they are good...:/
If i put headphones sound is good.
No short transistors or diodes .Please for some solution.
