  • Mark repairs a 1979 vintage guitar effects unit, which features a super rare Bucket Brigade Delay chip - the Reticon SAD1024. It doesn't go well, and did Mark get scammed???? FAKE component alert!

    That’s why I loved fault finding as nothing quite replaces that buzz you get when you switch something on after a repair and it works ! It takes a certain type of person to be a technician.
    It’s addictive lol. The more complicated the repair the bigger the buzz.
    At nearly 70 I can’t do delicate work anymore due to trembling hands and it’s so annoying, but I still have all the test gear !

      Just a thaught....... you could consider teaching a youngster who wants to learn, and he/she could be your hands?
      Im sure you could still get work if thats your profession, as mentoring someone is as though you continue your work through someone else, and eventually you could hand over your business to that person who would continue to provide help to your community 🙂 ?......

    to align all the legs before soldering them you can use a spare socket and press the legs into the spare socket and then solder all the pins at the same time.

    I used to work in a small music store in the 90s, and I had to deal with very similar repairs as this one. To be honest, I would have just hard wired the different chip with jump leads. Crude, but effective.
