Sight O Tuner

[John Ross]

Hi,
I remember when, I had problems with my old SOT. I agree with a previous
answer, where it was suggested that the knob had moved, on the variable
resistor. I changed all my switches once. It might also just need a squirt
of
contact cleaner. The wrong resistance will give a wrong frequency reading.
I don't believe Inventronics, services them any more.
However, in the ads, in the Journal give a name of Richard J. Weinberger,
Phone 623-584-4116 as doing repairs on them.
It was a good machine in it's day. I still remember using that little slide
rule.
