SWR detector diodes in Ten-Tec 509 & 405?

A few years ago I left a 509/405 connected to my 40M beam during a rainstorm.
Rain static took out the SWR detector diodes in both units (no other failures).
Ten-Tec didn't have replacement diodes available, and my one attempt at
substitution didn't come close to good balance or calibration. I've finally
gotten around to wanting to fix the units.
Anyone had experience with this situation? Be able to recommend a currently
available substitute diode?
BTW the antenna is a Cushcraft 40-2CD which appears to have no DC ground
continuity (that is, the driven element is isolated and fed thru a very simple
