I'm having problems with this charger. When I record, the power isn't enough and the voltage drops and a "hum" noise appears. If I push the voltage BATT, it reads below 5V and the VU lights start to blink and the meters too.
I replaced the big cap and thw two small ones that are in a small boards and resoldered all solders again, but the problem stills being there.
The last test I did is to switch the voltage selector to 100-130V and connect the charger to an external transformer (220 down to 125) and with this configuration, all works fine, but if I try to plug it directly to the main supply (selecting 200-240V in the switch first), the problem appears.
Any helo would be appreciated.
PS: I can't find the Z124 schema.
