[QUOTE="Ampdog, post: 769056, member: 144"] If pin 9 goes to an internal shield between the triodes, it is an ECC85/ECC88 type valve. 12A*7 types do not have internal shields. From the shape of the anodes I would guess ECC85 type or Russian equivalent (ECC88 and similar has frame-grid construction and typical inward 'dent' in the anode to bring it quite close to the cathode.)
