2019 300B tubes that are worth the money?

I can fully attest to the EML XLS recommendation of @charles1dad

Understood. Do you think that it is safe to clip it? None of the 300b that I have used - including my current Takatsuki - have this pin.

Hi Gary,

Your guess is as good as mine on that question. But FWIW, if there is a compelling reason to clip the pin, such as to make it possible to insert the tube into a socket that is recessed beneath a panel, I suppose it would probably work out ok if done with sufficient care. Including surrounding the tube with lots of cushioning materials to prevent or at least minimize any mechanical jarring, that for example might occur if the pin breaks off abruptly.

Also, my guess (and it’s just a guess) is that the pin does not go through the glass internally, so I suspect that the integrity of the tube’s vacuum would not be jeopardized by slight mechanical displacement of the stub of the pin that might occur if you were to do this.

JMHO. Good luck,

Best regards,

If your gonna to spend thousands on recent repros may as well buy nos vintage which are far superior and more musical. Cant beat vintage tubes ever. They are the best
