Very nice! Another box saved. SUPER YAY!.
Just out of interest....Where did you get the add-on transformer from?
I am sure that owners of GF-919 / 999 / 1000 boomboxes would like to know, as 100v is an unusual voltage outside Japan, as most of the rest of the world runs on either 110-115 volts or 230-240 volts.
I noticed that your one said:-
INPUT.............. 240V, 50 Hz,
OUTPUT.......... 100V, 50Hz.
Great! The UK has 230-240 volts, and this transformer would work great here. Provided that this transformer can provide a good 60 W of current, then the big Japanese boxes ( like a GF-919 ) would run OK with this transformer.
