Thanks for making this video. Very informative. I have an amp with valve issues. It’s under warranty and Thomanns has been superb to deal with. Cheers from NZ 😎🎸🤘
I have a Marshall DSL 40, I changed the main tubes with some new Tung-Sol EL34 Tubes. The highest I could get them to was around 24. Did I get some bad tubes?
I bought a v140 a few years ago. Just changed all tubes today, and the damn bias ports on the back don't read anything 😢. Never had to use them before so I don't know if it came from the factory not working or something happened between or my tester probes are not going in far enough, but they are like an inch long. Idk . I'm bummed out. I just keeped the bias where it was and hope for the best. Sounds good.
