Good riddance! I just aligned a 959b for a local (that wants to buy it from me) and all I can say is, NEVER AGAIN (and I'm glad to see it go)!
The slugs are so sensitive that it will convince you telekinesis is real.
I don't even know how to go about fixing that. Would I add more series resistance to reduce Q? I noticed these slugs are almost centered, maybe I need to change capacitors to get those slugs out so they are about 30% in when on frequency? Split the coil into two, one fixed and one smaller to trim (not really practical here)?
And then that frequency counter board soldered to another board on edge is just dumb. Also, I barely bumped the connector for the counter signal and it tore traces off the back of the board. And I can hear that EL driver too (not from speaker, just magnetostriction or whatever). Looks cool, sounds like it would put my dog through hell.
