  • Mark repairs a high end 1970's Stereogram. It only needed a fuse and a new belt! If only the diagnosis was that easy...

    My mum worked for Garrard turntables back in the 60s... they made some good kit in their day, the 401 was a beast. Lovely woodwork and nostalgia. Good job, well done and well done to the owner for cherishing this piece of antiquity.

    back in the 70s. my dad had a Fidelity UA5 music centre and we listened to the radio before leaving for school etc
    I managed to track two down with the intention of making one good one - then covid hit etc. Watching these you've inspired me to have another try, taking LOTS of pictures along the way so I know how they go back together

    My uncle has one of those to this day and I remember hearing it in the early 70s and loving the deep bass. About 10 years ago I was over there and asked him to put it on and it sounded terrible! I asked if it was faulty and he said no. Then I remembered that I'd worked for Audio Note for 10 years and every system in my house is Class-A valve gear, so I smiled and said "Tricks of the mind!"

      Your ears are well-trained now. Also we always remember past things more positively than they really were. So when you revisit them later.... you are met with disappointment. But having worked at AN, I'm sure you could tweak it to sound MUCH better !

      Dynatron stuff does sound good particularly certain speaker models and the valve amplified kit. All equipped with proper British Mullards. If it sounds bad he's probably got some dodgy caps and just got used it, it's aged along with him. Fix it for him!

Great work as always.

    The dynatrons were very good. I have about twenty of them, all with goldring lencos turntables. I bought them to pillage the Lencos but they are too nice to break!
    The amplifiers 24, 25 and 26 were a bit underpowered but the type (31?) you are working on are much more powerful.
    And the modular construction makes access very easy.
    Clunky, but well laid out for servicing. I love them .

    My Dad's Dynatron / Garrard turntable had issues with the pots going very scratchy. I didn't see you check the volume knob so I assume it worked ok and wasn't reported. That old system sounded better than budget to mid-range HIFI systems 20 years later. I'm gutted he chucked it out at the dump.

  • @sturm7130
    @sturm7130 Рік тому +1

    In a comment someone asked about use of silicone or petroleum based lubricants. DO NOT use Silicone based lubricants near electrical equipment. Silicone lubricant is Silicon (Si) based and electrical arcing turns it into glass (SiO2), an insulator. Not good for switches, relays or potentiometers. Silicone lubricant vapour entering these is enough to cause a problem. If you don't believe me, refer to Subaru's recent global brake light switch inoperative recall.

    Going back to the tape deck. I would of stuck a notch in it myself. As it just makes things so much easier and like any other tape deck.
    But OBVIOUSLY you would of spoken to the customer first, before you started modifying it.
    0:13 Is that a Record No25 by any chance? And does it have a quick release? Having a quick release on THAT size of a vice is sooooo handy, but if yours hasn't.
    Then just imagine how many times, over the countless years, you've had to finger your vice just to open it up enough, to stick a large part inside. But there are times when you didn't finger it enough on the first go, so the part won't fit. So THEN you have to finger it just a tiny bit more, to get the large part inside. The bigger the part, your never quite sure IF you've fingered it open enough to get it in on the last try.

    Mark, are there any problems that can be caused by machine oil degrading plastic or rubber parts? I ask because I have been wondering whether I should use silicone instead of petroleum based lubricants on such mechanisms. Great repair, though I’m still wondering what popped the fuse.

    • @Lyndalewinder
      @Lyndalewinder 6 місяців тому +2

      Can't give you an absolute answer Michael but I can tell you that you should not use petroleum products on plumbing plastics and rubbers at all as it degrades them - safest is to use silicone.
