    You said you didn't think it was a series strung set because of all the 6 volt tubes; for me, it was the big, honking power transformer that gave it away.

    The serial tag on the CRT matches the chassis serial tag so the CRT is original to the set. Replacments had their own unique numbered serial tag for replacement warranty even if made under the original TVs warranty period.

      picture tube tests good but all the other tubes are borderline dead... very odd. worth testing those tubes again in another tube tester?

    Also seemed peculiar that the tubes were very dusty while the CRT, including labels, looked pristine.

    I wonder if the picture tube was original but they’d got it blasted with a rejuvenator, hence why the CRT socket was unplugged? Possibly gave it a blast only to realise that the life was ran out of all the tubes?

      or, that the set was now visibly otherwise acting up so it wasn't just a picture tube problem

    I'm supprised that all the tubes are really ill, surely some are under less strain than others.
    There should have been a couple that were usable.
    Your tube tester shows bad for nearly every one, i wonder if the tester is ok.

    I've got an RCA TV very similar to this from 1964 that it works pretty good with just a few capacitors changed but for some reason it has a little vertical bounce to it that I haven't been able to fix yet. These TVs are cold chassis sets because they have power transformers.
    Mine is a UHF and VHF set.
    Maybe a shady repairman stuffed a bunch of used tubes in the TV back in the day and told the owner that they repaired it but they didn't and that's why it failed.

    Whats that knob in the lower left hand corner of Beltron, I presumed that filament voltage range, if so, should it have been set to 12 and not 6? I hate to ask a dumb question, but might that explain the super high emissions of the CRT - I cant find a manual for the Beltron to answer my own stupid question.

    • @JordanPier
      @JordanPier  3 ปีที่แล้ว +1

      Range isn't always accurate. Depends on current demand. Some filaments draw more current than can be supplied on the 6v range, so you have to go to the next range and adjust low

    Is there a problem with the tube tester? If known-NOS tubes aren't scoring high on it, I would wonder about that. It looks like a dynamic transconductance test from the print on the indicator meter. That will apply to any tube with grids. But the HV rectifier and damper alone in that TV set have no grids; they are diodes and the tester will test them by a different method. I say test the tester before worrying about the high-weak reading gridded tubes that have no other problems. The tester itself may have tubes in it that are themselves weak, and/or an internal calibration that needs readjustment.
    There's also a hacky way to "wake up" some tubes that are particularly weak -- as in barely budging the needle, not the high-weak ones -- but have no other problems. Apply twice their rated heater voltage (but no other voltage to any other elements) and cook them for 30 minutes or so that way. This can reactivate a contaminated cathode. Then retest at normal heater voltage. It might save having to get a new tube.
    But yes. Check the tester out on some known strong gridded tubes. If it's not getting into the OK region, something needs to be repaired or recalibrated in the tester.

    Dear sir i am having an AM radio which has MW, SW1 SW2 bands. Until last day it worked and yesterday it doesn't picked up any stations in all 3 respective bands. I have checked all the IFT transformers for any possible open circuit and soldering joints and checked the band sliding switch too. Finally i suspect the gang capacitor and checked. The upper terminal became loose and i soldered it properly. Even though the terminal goes inside the capacitor is not properly connecting the capacitor. I opened the outer top cover of the gang and just remove one moving plate, one static plate (sheet) and insulator and i don't want to mess the gang and put it back. After fixing the gang it still not working hence the entire receiver is not picking up any stations. Should I need to change the gang capacitor or is that possible to repair the gang. Please suggest sir.

    Even our shitty government (BLS) admits 169.95 in 1963 is over $1500 today, for whatever that's worth. I can remember we had a TV when I was a really small kid in the 70s, with only a VHF tuner and you had to put the channel on 2 and we had an external box for tuning in the UHF stations. I can understand why people wanted to hold onto stuff. Imagine paying 1500 bucks for friggin TV today!

      @@JordanPier When you showed us the back of the chassis, I remember seeing at least one black beauty up near the top/center. Might be a pause for that cause if so.
      I like to check for leaky DC on the coupling cap output with the device under test - running. Might be a little difficult in this case. Unless you have to remove that chassis to service the front pots. Eager to see your next episode. Like your show!

      I probably will have to address other problems. Right now I just need to get a good set of tubes in it. The calibration on the tube tester is good! So once the tubes get here we can see about getting this running and find out what else it needs!
