    Metrix scopes

    just got a late 90's one.
    just a warning to others.
    unless you intend a complete teardown and rebuild - dont buy one.
    because to remove the main board that fills the case and goes under the tube thats what you need to do!!
    even the fuse is under the tube!

    oh - and it had a RIFA in it.

      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...

      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...

      Fatman iTube (aka Dared MP-5) tube-buffered gainclone upgrades
      by linuxguru
      The Fatman iTube (OEM Dared, which also sold its own-branded version, the Dared MP-5) is a tube-buffered gainclone first introduced c.2005, to target the iPod market with a bookshelf tube setup. It became a huge success over the next ~15 years, selling over ~100k units worldwide to a market where it was often their first introduction to vacuum-tube audio on a budget.

      One of the Fatman versions landed up for auditioning a few days ago, and I must say that I was impressed with its form-factor, pricing,...

      RIFA safety cap PME277 - x or y?
      by mpwdhc
      Hi guys, new member here, trying to fix an 80s B&O TV which suffered a failure of the 0.1uf safety cap up by the power switch/fuse. This is clearly marked as x2. The replacements are half the size, but have the same rating.

      Having read about RIFA failure, I also ordered replacements for the other two caps. Now that they've arrived, I'm not sure they are correct. The originals are rated 4700pf, and are marked as follows

      40/085/21 GPF
      PME277 MB447
      CT5
      250V ~ MP
      LD2
      VDE reg nr 5201.212222

      Is this an X or Y cap?...
