Sharp GF 990G ghetto blaster
I will be renovating one of these next week, owner from new, was told only
100 came into the UK, probably 1982 from numerous IC "2.." datecodes. What is the use for the "sound processor" as no display, but seems to have its own 3V batteries for memory retention. http://i32.tinypic.com/10d6yxx.jpg The front comes away easily as do the 2 tape decks, hopefully just perished rubber bands and minor owner-mangling problems whole blaster http://www.audiocircuit.com/A-Images...990-G____-F-00 1-932-SHH.jpg |

If it is 1982 it uses a very early minidin connector, 8 way, to connect the
umbilical to the music processor (not sound processor) |

Other motor had .21127-A |

Back working again with all 7 bands replaced with new silicone rubber bands.
I wonder how long they will last. I read last week that silicone rubber is not as tolerant of cyclic loading, which dynamic use of this material I suppose is so, especially around the smaller drive bobbins |
