  • 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 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!

    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.

    I was the production manager at Dynatron when we made these. The production was initially in Maidenhead. It then moved to Kings Lynn and Fakenham in Norfolk. They thought the labour force would be cheaper there. They didnt make the cabinets. They were subcontracted from various furniture makers. Dynatron did not make the cassette unit. These were brought in from Philips in Holland. Not all they were cracked up to be. The Royal Warrant was the selling feature. Eventually the firm folded through poor sales and the parent company Philips shut the brand down.

    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.
