Albert,
I can only say thanks ; but thanks is not enough. Being 65 years old, I remember our family going out in the heat of the summer and leaving the screen door, as the only barrier between us and the thieves. Back then there were fewer thieves, we had to work or we starved. In the age of the internet, there are those who prey on those who look for the qualified suppliers of services, who tell us what their qualifications are; how can we check.
Albert, you've saved me the thought of dealing with an unresolvable problem. I won't have to feel like a fool for beliving, what someone who says he is a qualified tech, will do when I give him my charge card to do " what it takes," to return My Ampex to the stature it enjoyed in the golden age of analog.
Thanks , Ken
