This is why I've made several disks, looking for good quadrature by changing the number of slots, so they are the correct distance apart. But first, a viable, solid, stays adjusted, mount, which I do not have now. All stopped for the nonce, as I have to dig out the remains of a silver plating kit and see if I can rescue a variable inductor coil in a 60 yo Gates 1kw am transmitter, it has some burned wire, and is throwing it out of tune, cooking about 2 grand worth of 833c tubes way too fast or tripping the overloads that shut the cash cow off. Its a bailing wire & chewing gum fix because he is in the process of also bringing up a 25kw replacement which will turn this one off forever. Thats what I get for living as long I guess. We broadcast engineers that actually understand, and can fix this stuff are a dieing breed, at least locally. All the people I had working for me in 1984 and whose hands I could guide to do this when I came to WV and WDTV-tv, have since passed, and only one of them was older than I. So I'm the official 'it' now. The station owner is fully aware of that, and pays accordingly. Those 'tank coils' are made out of pure unobtainium in 2015. So I have to see if Tarnex & 0000 steel wool will clean it up enough to replate it later today. Not one of my fav activities as I may have to take the coil out of its holders just to gain access inside it with my fingers. Thats not too hard, but putting it back together is a PITA since each turn has its own slot in the 4 micarta bars that hold it at the proper spacing between the turns. I'd probably need to post a pix before the description would make sense. > > Erik > (Catching up on mail. Just back from a week on the farm - with another > ute-load of firewood.
