Hi Neal,

I'm not sure about the specs of that particular adapter. But since the VL-1 takes 4 x AA batteries (6V), you can probably get one of those "universal" adapters to work if you use the lower settings (maybe 3V, 4.5V, or 6V). Just have to check the polarity to get that part right.

Hi thanks,

What value of current would it need?

It says 6v 0.6w underneath so would that give me a current of 0.01A or 1000mA?

Also there is no indication of polarity - I wondered how I might find that out...

I use it quite a lot and I'm fed up of ripping through batteries!

The MIDI control is still working great by the way and can cope with some very fast arpeggios...

Power = Current * Voltage
(also known as P=IV)

So,

0.6W = I * 6V
0.6W / 6V = 0.1A

In other words, the keyboard may draw as much as 0.1A (or 100ma). The adapter needs to be rated for 100mA or greater.

If you take the batteries out, you can probably use a continuity tester to trace one of the battery leads to the power connector, in order to see if it's "center positive" or "center negative".
