    Does anyone know of or have a guide that references replacements for known tubes?

    I have inherited a serviceman's case with about 150 tubes.
    While some are listed as 6L6, 12ay7, etc., others are completely foreign but size, shape and pin outs are identical to "known" types.
    I have dozens from ITT, GE, Lindal, RCA that have what I am assuming is their designation for the same or similar tube, for example a 12ax7. Several have the equivalent written on the side of the box.

    I've searched Google but most of the Tube types don't return any hits.

    Any help would be appreciated.

    You could post the tubes here. Some of the people here might know exactly what you have.
    (it won't be me thought)
