It's such a nice feeling when a repair is completed. It seems that a possible overvoltage took out the tantalum capacitor (and the 8 volt receive regulator and the 8 volt transmit voltage) which shorted out that 14-volt line, which caused the coil to burn out. Glad you prevailed in that fight. Have a good weekend.

Hello Peter, it is allways a plesure to watch your videos. This couple "different" problems of the Radio look to me from a near lightning hit. All regulators are connectet togeter via gnd... even the capacitor witch was blown. I hat allmost the same ott problems after a BIG lightning hit pretty close to my house. The realy high tension came over the GND and produse the same faults in my equipment. But with schematics and a litle luck i was able to help me out.🙃

Tear drop Tantalum capacitor's, I don't know how many I have seen over the years that they short and burn like that. Some will emit so much smoke that you'll think something really bad has happened. I know designers use them for there low ESR rating but if it's in a not so critical circuit I've just replaced them with an equivalent electrolytic type.

5 problems but presumably it was working before it smoked. One common denominator is the 14 volt supply. Is it possible that either an operator error or a momentary power glitch could have caused all of these to fail at once? A momentary high voltage on 14 is one possibility. The 16 V cap failed taking the inductor. The regulator failed also which could have been overvoltage transient. Hardest to explain is the driver transistor for the TX switch. W5PZT
@stargazer7644
Жыл бұрын
The momentary glitch was the Tant shorting out. They are well known for this. I think that event might have caused a transient on the 13.8V supply regulation that contributed to the other failures.

Hi Peter, Another interesting video. You notice that the faults are all to do with 14 volt supply which would suggest to me that the 14 Volt rail has spiked at some stage causing the tant, voltage regulator and various regulating circuits to fail. ICOM mains PSU’s are notoriously problematic. I would check the condition of the surge arrest circuits in the front end of the PSU along with the capacitors and the usual stuff as it may just do it again. Best Regards John

@@TRXLab Hi Peter thanks for getting back to me. To be honest at this vintage I don't think switched mode PSU's age that well generally.
