Status Update: System Update: Just finished replacing all the electrolytics. I have a better appreciation for the tech's & businesses that do this ($$$). I'm putting together a re-capping kit that will have all the locations identified and differences discovered from the service manual + the...

>> ... just remove C232. That for that tidbit, I have not come across that one before. I'll think about it.

Thanks for your clarification. I looked at the schematic but I was not familiar with the pin outs of the TA7222AP. I used a 3300 uF for C172, a value that was discovered somewhere else. I'll proceed with your other recommendations.

loosecannon, I have one question for you regarding your recommendation of changing C181 to 1000 uF from the stock value of 10 uF. That's a significant increase. I see it is located next to the TA7222AP Audio Amplifier. What is the expected result of the increased value?

loosecannon, thanks for your input. I went to the wiki site and read the same about tantalums and shouldn't worry about. There is negligible deference in cost between 16v,25v,35v capacitors so I have been using values of 25v and above for all my replacements. I have collected information...

Status update: I'm half-way through the re-capping process and things are looking good. The frequency counter section has been done and I did an alignment of the PLL. I was getting 92.200 displayed at the bottom range and this has now gone away. I'm just replacing all the electrolytics. I have...

Hello, thanks for the feedback. >>as far as i remember, all these methods have worked for some and not for others. >>of course the problem is that it takes a fair amount of time to re-cap a radio. Yes, I'm beginning to see that bringing my unit out of long term storage is going to take...

UPDATE: its only been less than 24hrs since I brought this system out of retirement and now another issue has cropped up. The frequency counter is displaying 92.200 on all channels. From my extensive research on yesterdays problem, I came across an number of things to follow up on: 1)...

Hello, thanks for all the feedback. I was able to resolve the issue. As I was probing around the power supply section, checking voltages, I moved around a stiff wire connected at the output of the bridge rectifier and all of a sudden things lit up. Some kind of cold solder joint thing I...

Hello, I dusted off my old Cobra 2000 GTL and plugged it into the wall and it will not power up. The clock is displayed but the main power button will not power everything on. It was last working before I boxed it up a few years back. I've done some additional troubleshooting and the...
