    What really surprises me Frank is how many people want their old radio repaired rather than go out and buy a new one. And its obvious most people in Australia do take very good care of their radios. My question is are new radios that expensive in Australia? That's great you got this one to work so well. My first major transistor radio was a Zenith 1000 oceanic that had broadcast and 5 SW positions. It was made in 1957 and I got that one to work with a minimum of work. ua-cam.com/video/YFk7Km6kh6U/v-deo.htmlsi=Nukp7rgPxkzE4EA7

    Yeah Frank, we say shits and giggles here also but for some reason I cleaned it up a tad. I see that the American manufacturers aren’t the only ones raising their transistor count up for a selling point. That radio is only a 7-transistor radio because TX4 is a diode since the base and collector are wired together making it a diode. Thanks for sharing the video and the prints. The radio does sound nice and definitely a keeper!

    • @exeterslab7781
      @exeterslab7781 24 дні тому

      Hi, trying to remember but I think I just had the chassis only. If there's no grub screws holding the knobs on then they just pull off. Likely they're stuck fast to the shafts. One trick is to wrap twine/cord several turns around the base of the knob and start pulling. They can be difficult at times. I've also used a plastic lever designed for car trim removal.

    Never saw an aluminum encased Loktal tube before. The maroon colored jobby, an EF50/VR91 which were used quite a bit back then. Surprised after a tube pin and socket cleaning it works! New caps really fixed it. Too bad it must have an on/off switch on the line cord, one IF transformer , and find a long wire for an antenna. Real cheap design for sure Frank. Known as "city" radios.

    • @exeterslab7781

      I can't think of the owner's name ATM Steve, but he was renowned for cheap sets. He would buy excess cases from the manufacturers and fit his cheapo chassis in them. I don't see those loctals very often, but they were also used in a particular stomberg mantel as I recall

  • @roberthart8933
    @roberthart8933 Місяць тому

    Thank you frank for a nice video. I discovered the pigtails on most modern caps and others are tin plated steel. I guess it’s a fraction cheaper but makes the wire difficult to bend. I have read reports on the uk vintage radio forum of these leads corroding. Ironic the inside of the cap will last for ever and the leads rust through!,

    That came up really well good job. Where did you get the repro dial from? I acquired one of these recently and it has been recapped and is working. The dial markings have flowed down thr glass with time not helped by someone trying to clean the rear of the glass.! . There is still rubber wire to replace. The HT is higher than the manual shows at 225 volts but that seems about right for a 6v6 These are a most impressive set and the sound is good lots of bass. They were expensive , according to radiomuseum 27 pounds in 1948. Also the converter valve doesn’t look like a ech35. At one point you did replace it with a red one. The ech35 has double the conversion gain of a 6j8 or 6k8. They are all pin compatible though.

  • @kenf8563
