Be sure to add me to your favorites list Archer 6 Volt Power Supply for the Casio VL-Tone, Casiotone VL-1 Micro Keyboard. This listing is for an 80's vintage power adapter in very good condition. This is a nice replacement for an old Casio power supply, that will work for the early 80's vintage VL Tone / VL-1 / VL-5 micro-sized keyboards and perhaps other models as well. This one's made by Archer, one of the brands that RadioShack has sold over the years. Know that Radio Shack also made versions of these little keyboards too, called Concertmates, and this unit was used with those. Will work for other instruments and other electronics that require these specs: Output of 6 volts DC 150mA, with a negative tip (-), with proper sized barrel-type plug for these instruments and others. Thanks for looking and please check out my Store!
