Hello guys need help with 1992 cobra 148gtl PC-412AG looking for part number to d-78 thanks as some schematics I have researched do not have it thanks.

Think that sonoma will have that info . . .

d78 did not register and I searched and only found up to d76. not a D78. even looked in the sams and did not find it. what section is it located in? you might try a 1n4148 and see if it works. most are 1s1588 and they will change to a 1n4148.

Will have to pull it out looks like a black diode with blue writing.

Can you take a close-up pic of where it is and post it?

I got to thinking about the tr296 rci radio that has the same board as a cobra 148. it has the diode D78 diode. it is a 1n4003 diode. the same as D55 the protection diode. it is a black diode with the band on the end as you mentioned. the tr296 has the same board in it as a cobra 148. only a little newer than most 148 5 pin radios.

here is the service manual for the 296 radio. the board will be the same as in your radio . just incase you want to look at the schematics and manual.

this one was a little tricky to find. made me put on my thinking cap to find this one. I have a rci tr296F radio which is basically a cobra 148 board and it is just a little different.
you are welcome
