Ok, after changing Pinch Rollers and Heads the GF777 works perfect, it sounds crystal clear with highs on both decks, it's like a HiFi System. I screwed the screws of the woofers when it was opened, they weren't tight anymore... Now I got the feeling that the Bass is much harder and clearer then before. It's a real Bass Monster, sure it was before, but not so deep and clear, maybe it could be the "new" heads too.

I found them on the attic, they lived in an double tapedeck by fisher from the 80s but when it broke I took all parts i could need. I tried to build them onto my GF777 and they work perfect on it. Sure they're no new ones, but they are in really good condition and could do their thing for a few years on the GF. The Sound is so awesome now... I thought I got a new Ghetto Blaster...

Some people say the GF777 has no highs, maybe their heads should be replaced or they have to adjust them. The old ones were so worn out, the tape had ground a "rail" onto it, I can feel it with my finger nails.
