Questions about tubes and gear that glows. FAQ

Thank you

I was not aware of this.

I have a Knight 600A I got cheap, over twenty years ago. Some years back I pulled the Mullard EL-34s out of a working Dynaco ST-70 and put them in the tester because I was curious how they'd test.

On the last of the four, the needle moved to good. I pushed it again for another good. A third push (don't ask me why I tried a third time, 'cause I don't know) the needle dropped, and the tube was shot.

I posted, asking if testers were hard on tubes, and was told it was probably just a coincidence. I always suspected otherwise. A good original Mullard EL-34 is a tube you do not want to learn a harsh lesson on!

Thanks.
