I've read that if in storage sitting on the feet on back / front facing up , that some lube ? in the main oscillator flows over time and you can loose the signal , have you come across this ? --- End quote --- I have not heard of that, wow... |

I haven't seen it myself but I understand it can take months(!!!) to get back to normal. Otherwise, a fine signal generator and you can have mine when you pry it from my cold dead hands! :-DD --- End quote --- I feel the same way, as a matter of fact I would love to have two. |

All photos are gone Sue, suggesting to use forum's attachment feature rather than external hosting. |

It has been a long time, and I am well aware what a pain in the posterior repair of the thread would be, but I would like to plead with you to take the time for the sake of future restorations. I had the pleasure of reading this thread before the photobucket fiasco and it was absolutely top notch. |
