Thanks Banquo,

Vintage DD turntables. Are we living dangerously?
Halcro, You wrote, "The ICs were more difficult as many of the test figures in the Victor Service Manual didn't make sense or were simply wrong." Are you referring to the DC voltages on the pins of the ICs? I ask, because I measured some of the voltages at the pins of one IC that is suspect, and they do not at all match the predicted readings posted in the Service Manual for that IC. This led me/leads me to believe the IC may be faulty. But if my interpretation of what you wrote is correct, maybe I need not worry about it, unless or until I have further evidence of its malfunction. Please confirm. Banquo, where do you live, and who is your tech? Is it Bill Thalmann? Thanks. |
see above: 09-12-15: Banquo363 He's in Oregon, so you'll need to risk shipping the table. |
Lewm, From what my Tech showed me, I'd be firstly inclined to not worry about the values you are getting when you test some of the ICs. He showed me three or four values in the Service Manual that he said bore no relationship to those he measured.....and the ICs he measured, actually worked perfectly once the solder joint problem was remedied. As I surmised above....with the TT-101, firstly suspect a poor solder joint before thinking 'bad' IC or transistor. |
