Anyone happen have the zener specs on the 6201? I happen to have one here
with a nicely-burnt board, it appears the solder job and traces held but I'll lay odds that the zener is open considering that it is not only no longer amplifying it also occasionally likes to spam the original signal back on the incoming phase forever!

On closer examination it turns out that both pads of the zener had >separated from the board (a good trick considering that one of them

Is this a 1 watt 1n47xx ? I have an ACT CR225 also and considering preemptively replacing with a higher wattage zener.

Ironically, the Leviton 6201 that the ACT CR230 replaces in my system
(via a
detour with the factory-supplied Leviton HCA02-10E when the 6201 failed
)
also had darkening around the zener.

Leviton didn\'t bother to specify positioning the zener away from the
board
so as to increase dissipation and reduce heating of the board although numerous _other_ discrete components were sloppily inserted and not snug against the board.
