    Tube tester: Sencore MU-150

    Jay, For sure the 3 wires capacitor is on the PCB. No need for it. I do not recall the rest, it's been too long.

    NE-2 90VDC. Should work yes. This is what I used.

    Removing labels on Heathkit amps and transformers

    Water is best at first. Soak it with water for as long as you can, days if possible. It should get very soft and then easy to remove.

    Utracer help, doesn't work

    Hum. If I may, the ferrite has to be placed as close as possible to the socket. And you can add multiple, especially grid and plate. I added multiple to tame what you have on my UTracer 3. And your bias is too negative for your 12AX7 test, that's why only the -2 is showing.

    RIP Terry. This is a big loss for all of us.

    Try on the socket for that tube giving you trouble. Yes more ferrite the better. Can you take a picture of the wiring while you are there? Nice case you've made.

    Utracer help, doesn't work

    From the google group: "it is very possible your tube is oscillating during the test. It is very common, and discussed in the documentation. In most cases it is easy to fix; take a small toroid core, and wind the grid wire a couple (2 or 3 is usually enough) around it, and try again."

    And your third graph shows oscillation. Have you used ferrite beads close to your tube's connection?

    Awesome. You're welcome. I didn't know side mounted tube socket could be purchased these days. Good luck with the calibration.

    Trying to decide what power amplifier I want to purchase to pair with my Mcintosh c220

    I would go for a MC275, vintage or a VI modern version. Awesome amp. If you go vintage, a full restoration is in order.

    Hi BassoJay, I installed a 1A slowblo fuse inside the unit, and kept the power socket, and so far so good: never blew one. For the socket, I made used an aluminum sheet and cut a plate, made the socket hole, and mount it to the board with 90 degree angle bracket. I used a Belton socket with...
