    pile of vacuum tubes... what to toss?

    I wonder how many people are in the same boat...

    I have a pile of vacuum tubes I've collected over the years. Now the question is: which ones should be disposed of, if you don't have access to a tube tester?

    I had swapped a tube into my AR-3 and noticed that sometimes the audio would cut out. Rapidly turning the radio off and on through the control knob "fixes" it, but pulling the plug and replugging rapidly does not.

    I randomly swapped in another IF amplifier tube, and it seemed to have "fixed" it, suspecting the tube that I took out may be weak and perhaps should be binned. It's the 12BA6.

    I wish the pinouts of tubes were consistent! I suppose luckily most 7-pin tubes have pins 3 and 4 as the heater, though cathode, plate, grids can be pretty much anything...

      Don't toss them! Put them on eBay for someone to use in a "crafts" / "art" project.
      Unfortunately, I can't answer your other questions - I'm not versed in tubes and tube gear.

          That is true, I had forgotten some people still want them for art and craft projects

          So even more important that I can somehow filter out the bad/weak ones, so they can go to a use that's no longer rectifying, amplifying, or regulating

              Hoover FM216LI cordless vacuum refuses to charge
              by flat-earther
              I have a Hoover FM216LI cordless vacuum which isn't charging its internal battery.

              I opened up the unit, and it has 6x Samsung ICR18650-22P cells connected in series.
              5 cells were at about 3.3-3.1V. one was at 2.4V, so I assumed this cell was bad that's why the vacuum wasn't charging so I replaced it with another 18650, but after that the problem still persists, the vacuum turns on a bit and then cuts out since the batteries are empty.

              So I think the over discharged battery wasn't the culprit, it was a symptom of the unit not being able to charge its batteries....

              ZD-915 vacuum pump motor mount service alert
              by sam_sam_sam
              If you have this Desoldering Gun Station there is something you should be aware of the two screws that hold the motor to mounting for pump can come loose and make raddling noise

              One note this unit has been repaired already once because of switching power supply regulator ic chip failure
              Now this with the vacuum motor mounting issue yes I give this Desoldering station a very hard work out and use about every weekend to do some type of project

              The fix is taking the vacuum pump assembly out and take the metal cover off and you will see the two screws on it

              ECH81/6AJ8 Vacuum Tube Question
              by Schoenradt
              Recently I acquired an Eico HFT 92 AM/FM radio made back in 1958. The unit has had some decent modifications done such as replacing the rectifier tube with silicon diodes and replacing the main filter capacitor with electrolytic capacitors. When I powered it up FM wouldn't tune past 105Mhz. I checked the FM tuner front end assembly and found a capacitor not soldered to the coil from the Plate B+ to and ground on the other side of the coil. Some calibration was needed on the trimmer capacitor on the tuner. My question is AM is extremely weak. When I tap on the tube I get all kinds of snapping and...

              B&K 707 tube tester. I need help.
              by DCJack
              Hi everyone!

              I managed to get my hands on a rough condition B&K 707 for "the best price" because it was not working. It's my first tube tester and I'm really wanting to get it up and running. I downloaded that manual that has the schematics and tested every resistor and capacitor and replaced the ones that failed. I replaced the missing 83 rectifier tube with a used but tested-good one. I also have a number 80 rectifier tube that I have used in tests before I found the 83 tube.

              Initially I noticed that I was not getting the red on-light to turn on, but it...

              Replacing the WiFi module on a vacuum cleaner iROBOT i7
              by AlexVG
              Hi,
              I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.

              I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
              (This board does not respond, only the LEDs light up in a circle.
              The liquid damage is catastrophic and restoration is impractical).
              (I bought this board to get the WiFi module and camera).

              The boards are completely different in the installation of elements, even the connector for the WiFi module is different.

              If...
