Haven't posted here in a long while... life happens!

Today I was offered two boxes that have made me very curious. Thought I'd ask about them here:

One was a Sharp GF-535. The thing looks identical to a GF-9000. Are there any differences between the 535 and the 9000?

The other one was another Sharp, which looked like a VZ-2500, with red woofers and surrounds, but in the middle section was some blue stuff and, in large print (resembling the "BSLT" lettering found on some Euro models) the designation "V2". In small print, where the ones I have at home say "VZ-2500", this one said "V2-V2". I didn't get a look at the label on the back, although I can within a couple of days. Can anyone enlighten me as to the "V2" version of the VZ series?

Any info appreciated. I haven't bought any boxes in months, since filling up pretty much every spare nook and cranny in my apartment with them, but I'm thinking of breaking my self-imposed ban and getting these. The old boombox itch is just getting to where it might need to be scratched a little, ya know? Just would like to know more about them, first. Thanks.

Hi Man..i dont think there is alot of difference between 535 and 9000,i think the 535 has 2 more sliders than the 9000,and the 535 will only run off 100v (no voltage selector)
the vz,i`ve had a 2500 and i`ve got a vz2000,mines got red woofers,all the controls on the 2000 are on the top,are you sure its not a 2000 ?

i've seen V2 come up on the bay - but don't know what the difference between that and the V2000 - V2500 - V3000

GF-535 is part of the "Searcher" series and is from 1981.
