Antenna Protection Diode
I am restoring a Kenwood TS-930S. It took what appears to have
been a near lighning strike. The mains fuse and a regulator were blown. At the coax input to the unit there was a blown diode -- a Diac I believe. It appears to be a protection diode and is connected between the coax input and ground. The Diac was shorted and the result was very low receiver sensitivity. After removing it, the receiver worked fine. On the schematic it is listed as D67 and the listing shows it (somewhat blurred) as D5A-44??. Between the parts list and the schematic I am unable to tell just what it is. Does anyone know of a good protection diode that I can use as a substitute? The unit is now working fine and cleaned up beautifully I just want to replace the darned Diac to complete the restoration. Thanks in advance for any assistance. Irv VE6BP |
