    Happy New Year to you! Great job on the tuning condenser (and cabinet too). Yet again, the magic of 3D printing is proving it's worth! And a helpful lesson in the importance of reading schematics! 😅

    Happy New Year! The cabinet looks fabulous and great work on the pulley. The audio quality from the FM section is fantastic. Looking forward to the next video!

    Happy New Year, Manuel, to you and yours. Can you send a New Year present of some Madeiran weather to cold, sleety Scotland. It's a bit driech at the moment, as we say here. However, it's the perfect excuse for staying indoors and catching up with your latest wizardry.
    It looks like whoever was in there before you simply lifted out the tuning capacitor and didn't do any other real damage. There must be another of these out there somewhere has had a heart transplant. A lovely job of finding a suitable replacement and the case is superb now. I'm very envious of the lovely radio you've brought back to life. I particularly like the look of European domestic electronics from this period - so clean and simple. Looking forward to episode 3.

      Yes, we lack a lot of stuff in Madeira, but great weather isn’t one 😊 enjoy the cozy indoors. It’ll get better 😊

    Good find on the tuning cap. Ground is black, right, black is ground (2:04). That's your USA electricians job opportunity down the Swanee, ho, ho.

    Looks like your year is starting well Manuel. Nice luck with the tuning cap values and then hitting the Goldilocks diameter of the pulley wheel. Try the Lottery while you are on a winning streak.🤞 The truth is we make our own luck by making good choices based on experience and knowledge and you have both in abundance. HNY

    That's often the very time involved way to go, but its well 👍 worth it. It makes sense to replace a radio 📻 tuning capacitor when no others are available. Great 2025!! Best wishes!! From your friend, Jeff!!

    Happy New Year. You know that the slots on the outer plates of the capacitor is for fine tuning the gangs to each other. Have seen some with strange bends and long wonder why. Thanks for all the great videos.

      Those plates are used to improve tracking a cross a dial.

    Very good. The cabinet looks great Manuel. I can't understand how the side on the capacitor with more plates has less capacitance. I have never measured a variable capacitor with different numbers of same size plates. No doubt electronic sorcery. Thanks Manuel 😊

    • @electronicsoldandnew
      @electronicsoldandnew  วันที่ผ่านมา +1

      I had a closer look, and the plates seem to be ever so slightly more separated. That would make sense.

    Manuel hope you and your two ladies had a nice time over the holidays, and the New Year wealth and happiness to all. What luck in having a stash of parts radios to cannibalize, gone are those wonderful days when you could open a catalog and order parts for tube type radios and TVs.

    Wow ! This is a rather complex project Manuel, you're doing great, not sure I would have tackled replacing the tuner condenser myself not being as advanced as you are, but if I ever do have to replace one, this will be the video to re watch :-). Can't wait for the next episode now. I just started on my 1st Telefunken, it has a ''Funky'' chassis set up let's put it this way...
    Thanks for sharing and happy new year to you and your family.

    Happy new year! The original capacitor seems to be one type of that grey painted "Hopt" capacitor used in many German radios in the 70-80's (as in many Norwegian ones) Much adaptation, but yours will work fine

    Hello Manuel. When capacitors are connected in series, the linearity of the scale will be disrupted. The scale divisions will not match, especially on short waves. It is better to bend the split sectors on the rotor and adjust the required values.

    Man, well done on that pulley you designed! And picking the VC was a fate of luck! 👌 And the cabinet is so beautiful! 👍

    Happy New Year! If you used that film cap in series with the oscillator part of the tuning cap, I think it will be a problem, especially on SW. One thing, that type of film cap is intended for lower frequencies, like audio, its turns are not shorted with schoopage and therefore it probably has series inductance that might be significant enough on SW. Second, if it's a PE dielectric cap, its temp. co will be too high. Even if it is PP.
    The temp.co is a percentage of the whole value of the capacitor, and its 6.8nF capacitance is many times higher compared to the tuning capacitor's, so that few percent change of the 6.8nF in a, say, 20°C range of temperature change will be significant compared to the 10-430pF range of the tuning capacitor. I would rather use an NP0 ceramic, or a silver mica in that position.

      👍 I agree. The cap is only temporary.
