HW- 8, no output

[Tom Buchanan]

Hi,

I just recently got a HW-8 to restore at a hamfest.  It has zero output.  It appears to have been well built, but appears high voltages have been on the board.  The zener diode was cracked and it has the 4 watt mod for the final using a NTE 488.  I have yet to find a source for a 36v zener diode (VR-36 & Heath part #56-55).  I will also be replacing the final transistor.  Anyone on the list know of a source for this zener diode or a suitable replacement?

Thanks & 73,

Tom KG4KGY
