Question about Boss PSA-120 (761294015735) Power Supply
When using 9vdc battery,the unit works just fine, but when i plug in the psa120 boss power supply, the red power on light goes dim.. and the sound from the unit is weak and distorted.... any ideal what may be my problem.....i have two units that are doing the same thing......
It is likely that the power supplys have blown diodes or capacators
and there is too much ac in the signal ,
or the power supplys you have don't have enough wattage to power the units cleanly. did they ever work.
instead of using a power supply with 300ma or so use one that has 500ma or better 1 amp even.

Hello! I'm having the same problem with my Boss CS-3. Was it the power supply that was the problem?
