    Looking for a 12B6 for my Deforest W05/41 Ch= 10DA517 or a 12Q7 can work if I modify the wiring.

    Les,
    I am puzzled why you would need to rewire the socket to go from a 12B6 to a 12Q7.

    They have the same basing diagram.
    Is the 12B6 one of those special Rogers tubes ?

    Hi John. I’m basing this on advise on the radiomuseum site where it says “Particular Rogers type. In a GE list of equivalents it should be replaceable by 12Q7, but that is not correct, since base and wiring must be changed. ” Source: https://www.radiomuseum.org/tubes/tube_12b6.html
