Hi, the 9 pin has a fine SOVTEK (12AX7-I think ), the 7 pin has no markings(rectifier?). If you recognize, please send info.

Thanks A

Looks like SOVTEK 12AX7W - from pics on net. Has that type of getter.

Can’t tell if that 7 pin is a recto or not with it not standing up .

Put them in the freezer for a while. When you take them out, very briefly, there will be some amount of condensation on the glass. Look for the shadow/outline of anything that may have been printed onto the glass. You might get lucky.
