I searched for FH7 on google, because I want it since I'm a little Child but i heard that it is a componentsystem not used to be a ghetto blaster, only AC Power supply, but a few minutes before I found this interesting link:

http://www.thevintageknob.org/SONY/sonyvault/HELI/HELI.html

Two power-blocks could be used: EBP-78 for outdoor use and AC-78 for indoor.

does anyone know about the EBP-78, and has anybody such a unit? I'd like to get it then.

Cheers, Tobi
