    I have a older TEKTRONIX 475 Oscilloscope that needs repair, the sweep will not trigger either
    channel 1 or 2, it auto sweeps fine. I have checked & re-plugged all connections possible with no
    improvement.. Might anyone have any suggestions as to a potential. reasonable, cheep, repair,
    recalibrating person in the central Michigan area? I have checked with Tektronix repair locations
    in the north east USA but there minim prices are in the high hundreds just to check it out.

    Thank you.

    Also a post on the Yahoo Tek group would be very, very valuable.
