Thank you! I will search for the problem part tomorrow.

Driver bias I can get to 20k no problem. The middle will only go to 13k and the third will only get to 2.73k. The middle one gets hot almost emediately. 100k trimpots, could one be bad or maybe a bad resistor? I haven’t changed anything other than the driver and finals.

Oh the fuse in my truck power cord should be 5 amp. Power cord came with the new radio so I'll double check it.

Yes sir. I've never tried it that way. I will definitely give that a try this evening, Thank you very much. If this doesn't work for me, it's going to a tech and put back to original stock with bipolar transistors. I don't care for the MOSFETs myself, yeah you can get a few more watts but too...

Ok here’s the whole rundown. I ordered a new general lee in February, from a shop(advertised as a shop anyway) and paid extra for the peak and tune. Received it a month later and it came with a 520 driver and 2 fqp13n10 finals. Palomar max mod am regulator. Radio worked good doing about 60 w on...

2sc1957,2sc2314,2075 and 2029. There’s a few more I was gonna try also but they weren’t in stock. I wrote the numbers down at my station but I’m not at home for a couple days. I was gonna check mouser and digikey for the others

It was 9.6. Turns out, I never checked the voltage while I had the driver and final desoldered. I desoldered the final and voltage came back to 13.7. I did order a few transistors from rfparts but the 2078 was not in stock. I don’t remember the part numbers but I’ll check my cart and post them.

Yeah sorry. It is a cobra 29 LTD. I'm giving up for today, mainly because I have to hit the road in a few hours but I appreciate the replies. I'm gonna order some drivers and finals today and try again next weekend.

Yeah I found some online from a few places. I've ordered a few parts from rfparts before and they were good so I'm gonna give them try. So many fakes floating around these days. The final checked ok but someone has been in this radio before. The driver was changed to a c2314 and some resistors...

I don't remember asking anybody to Google anything for me. If you think I haven't googled, read forums, read manuals, and tried fixing them myself for countless hours at night on my days off you are dead wrong. See if you read my post I clearly stated that I'm only a few months into a hobby I...

Driver and final test ok. Voltage is only 9.3, highest anywhere, power supply is set at 13.8. obviously something is blocking some voltage. Well, maybe I'll learn something today lol. Gonna start checking it out

Thank you. I will pick up a new speaker on my way home tonight and try it

Thanks. I do have some schematics at home for a few cobras and a galaxy I believe. I'll take a look at em tonight.

I am new to repairs and only recently got interested in fixing and toying with old radios so please excuse me if I sound dumb. I have a few older cobra 29s and a few other brands l would like to get up and running. The one in question powers up and has some nasty static on Rx and the light goes...
