Lou,
There isn't much inside a Bird slug, as you know. I'm curious why the diode and terminating resistors were replaced. Did you repair the slug yourself?
There is obviously too much coupled voltage produced by the slug. About all that I can think of is that (a) the coupling of the sampling line to the main line is way too close, as if it were maybe a 5D slug, or (b) the terminating resistor's value is much too low. How was its value determined? Presumably it was open-circuit, which is why it needed replacement.
For what it's worth, I disassembled my 50D slug and measured the fixed resistor's value. It is 18.4k. I hope this helps. I've attached a photo for your perusal.
