  1. In case anyone was pondering hard on the question and about to reply,
    don't bother - it's sorted. ;-)

    Turned out to be a fault in the VCO power supply - the same cap had
    failed in each one.

    How did you locate it? (freeze?)


  3. I probably never would have without a circuit diagram - but I had a
    working tuner so compared voltages and waveforms etc and got lucky.

    Certainly lucky to get a circuit diagram of anything these days - annoying
    because the things always start off from that stage so they always exist

  5. At one time you always got one - at least with decent makes. Why you
    don't now I'm not sure - it's not as if it would prevent piracy.
