I am not really sure about this, but it may even work without modifying the variable resistor, since 5V is within the range of what 4xAA batteries can provide.
For the same reason fake batteries like these should work without issues (i am definitively gonna try this sooner or later).

are the voltage regulator and the diodes required for the batteries?
If i only use the AC adaptor can i just lower the resistor?

hi, i've seen from the service manual here that the VL-1 has a variable resistor labelled "VR1" that (i guess) should allow 5V power input.
Since 5V/USB power adapters are everywhere nowadays i'd like to do the same mod on an old PT-10 keyboard, if it has the same resistor.
I also guess i will need to add a resistor to use the batteries after that...
