so this is on the cobra 2000 board your speaking of? If so I will get it replaced with a higher voltage value.

ok thanks everyone for your input. I really appreciate it.

thanks for your input, radios works fine. I'll just leave the 12 tants in there.

I have a Cobra 2000 GTL I just finished recapping all electrolytics on the main board. Now from what I have heard and read is that the tantalums should be changed out also before failure. My question is has anyone swapped out all the 12 tantalums for electrolytics in the Cobra 2000 before?

thanks for your response. I installed a 100uf 50V in LOC C367 seems to be working just fine.

still need help on this issue

thanks, still trying to find out about loc c367 from the factory there is a mylar in there but on the silk screen on the pcb board it has a electrolytic cap stamp on the board.

I have a in good condition dx 302. When I got it the audio was terrible sounding. I did some of the audio mod that I found online. I put in a better speaker and raised the value on 4 electrolytic caps. My question is that at LOC C367 there is a 1uf mylar cap there and they say to replace it with...

I will check, thanks.

Also the wire has been removed between L39 and TP7. It's not there. Should this be put back to stock configuration? So how is power being sent to the final? I'm assuming it's being supplied 12V instead of 8V cause the wire isn't there.

thanks Frank, I'm going to leave the radio the way it is. I'm not a tech but know some. So TP3 is a typo in my service manual? Wow ok thanks for your valuable input. I appreciate it.

ok thanks, you know your radios! I got the bias adjusted on the driver (30ma) but not the final only because the wire isn't there anymore. I guess I won't know the bias of the final, we'll see how long that final lasts. The bias final VR is at position 1 o'clock

thanks for that info, I didn't know that.

I have a 1986 model year Cobra 2000. Final quit working. Just replaced the C1969 final with a used one that I had and works good. My question, I want to adjust the bias. My 2000 service manual mentions a TP3. There is a CRD on the pcb there and a hole but no post for a TP3. This is for the...

Thanks I have a NTE236 and a HG1969 going to give those a try first.
