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 high and 40 low. Dk was 2 on low and 8 on high. I always ran it on low power with no amp, just bearfoot. Radio got good feedback as far as getting out but the receive was noisy as hell. I did a Schottky diode and NTE107 recieve upgrade which helped a little there and it worked fine for a week. Then I notice the meter fluctuating under transmit. Thought maybe the mic was needing some attention. Then all of a sudden everything sounded like they were 50 miles away on recieve, I checked my work and reworked a solder joint. Went back to working fine. Next day, it stopped transmitting, both finals shot, and regulator bad. I put a regulator out of an old magnum s3 and tried new 13n10s with new irf520 driver. Even tried 2030s. Changed driver to 13n10. I mean I tried all my options but it simply heats up the regulator instantly and smokes up one final. It did not have any ekl companion parts only one zener attached to gate and drain of the driver. Tried with and without that. Tried a resistor and en369dr on the driver which helped a little bit but still overheats. I can’t seem to get the bias right but as I said when you key the mic it dead keys, about 4 watts but overheats almost instantly so adjusting anything while keyed up is impossible. These parts came from trusted distributors and not eBay or amazon so I trust the mosfets are real. Any help would be greatly appreciated here, I’m not a tech by any means but I love trying to fix old radios. Just don’t work on mine lol unless it’s completely necessary, nearest tech is a long ride down the road. Thanks and hope I covered everything
