Hey guys, having trouble finding info for diode D78. I can find it on a schematic but not on a parts list to tell me what it is. Anybody know this one??? It is inline with the MB 3756 regulator (IC4) HELP!!!
Thanks!! Was driving me nuts!!http://www.cbtricks.com/radios/cobra/140gtl/graphics/cobra_140gtl_142gtl_148gtl_tb1226.pdf
It is the SR1K2 diode from pin 1 to pin 2.
Thanks. Mine is a 1991 Philippines model.Radios made before that bulletin were supposed go get D78 added on the solder side of the pc board. It serves to prevent mysterious failures of the MB3756 chip. All radios built after 1979 came with this diode.

Incoming Region Produces X3 Solar Flare |

Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned |
