    I hope you are still fine under difficult time.
    Apart from it, good job for the repair. I like your manner you always start with cleaning up the body before doing repairs. Very neat way!
    The electrolytic caps are all bottleneck for Sony equipment in this era (90s mostly). And it is wise to replace them with SMD capacitors. Suggestions are: 1) tantalum caps are good for performance but still have possibilities to break in catastrophic manner as it fails in "short" mode between VCC line and ground. 2) the most weak caps are within DC-DC converter which is used for tuning-voltage supply over varicap. In this SW7600's case they are inside shielded tin can so difficult to replace in fact. If it was not replaced this time, the next time you better replace it first.
    GL and 73!

      Thank you my friend! If you follow the link in the description, you will see that I am not only changing the capacitor in the DC-DC module, but also making a mod there. Tantalum capacitors do not last forever, but I think they will work for another 20 years.

    ICF-7600 the most perfect version that SONY has produced. I regret so much that I sold it in 2005, the 2002 model. I have tried several brands and models, but ICF-7600 is NUMBER ONE ⭐⭐👍Then comes the ICF-55⭐⭐

    The early Sony 7600 from 1983 onwards to 1987 didn't suffer from this problem as no surface mount capacitors were used.

    Hello, I can't stop watching your video it's so encouraging. I'm going to buy the same radio, it has a fault, it doesn't pick up FM, can it be repaired if I change the same parts as you? THANKS

    • @ukrainehamradio
      @ukrainehamradio  Рік тому +1

      It seems to me that before starting a repair you need to make sure that you understand how the circuit works, how to determine if the parts are ok or faulty, have the proper tools and skills to replace bad parts, make measurements and alignments.

    • @34yacino
      @34yacino Рік тому

      I have the inspection tools, and I have the soldering tools, but unfortunately I don't have the skills 😥. If not where did you buy the (yellow) parts?. Thanks
      Another question, if the radio doesn't pick up FM, do you think it's fixable?

      @ukrainehamradio  2 роки тому +1

      I buy capacitors in an online store. There are a little over two dozen of them. The easiest way is to just look at the list of electrolytic capacitors in the service manual. The new tantalum ones are size B. Preferably a little more voltage.

      In this receiver, I left the Rubycons because they had good parameters. In another receiver, I replaced them too, at the request of the owner, but it is difficult to find a good replacement in the right size.

    З відео не зрозуміло чи усі конденсатори довелося міняти чи то був якийсь ключовий і того достатньо? Взагалі то дивно, вони схожі на твердополімерні в яких немає чому сохноти і ресурс напрацювання в них = декількам таких гаджетів..

    • @ukrainehamradio
      @ukrainehamradio  2 роки тому +1

      там звичайні SMD електроліти не кращої якості. головна проблема не у висиханні, а у витіканні електроліту на плату та роз'їданні всього на платі. також відбувається зміна параметрів. зазвичай краще замінити одразу всі, оскільки всі вони приблизно в однаковому стані.
