I've had 2 GF555.. I bought one in 86/87, bought it from a friend, it had a Blown Amp, i went to the sharp parts centre and Bought a new HA1392, i only lived a few miles from the Main Sharp Factory in Manchester, and just up the road was a place called willow vale electronics that sold all spares for sharp. it was awesome, i used to go there all the time.. when i repaired the sharp my friend that i bought it from seen it working and wanted to buy it back, i said no at first because i wanted to play with it for a while, but eventually i sold it back to him. great radios.. just a shame about those forever missing aluminium plates from under the Tuner, why did all those people just throw them away instead of either gluing them back on or just tape them to the back of the stereo so someone else could fix it back on. someone needs to reproduce them, so many missing from GF555, also the cassette door plates as well..
