NOS in original boxes. 1960's vintage.
NOS in original, old style, boxes. Early 50's with gray plates and massive D getter. Each tube has a Ministry of Finance ("Ministero Delle Finanze") colorful paper stamp attached which is blocking the production codes. Month/Year on the stamp is "Giu 53". (July '53 in Italian).
60's vintage blackplate, high grade 12AT7 is nice original boxes. Excellent for Fender reverb drivers and phase inverters. Highly recommended!
Manufactured in Mullard's Mitchum factory in the early 1980's. Nice military stock. Original white military boxes. Try one of these in your phase inverter or reverb driver socket (only if your amp calls for 12AT7s in these positions) in your Fender amp for a real upgrade in tone! Also superb in audiophile equipment, tube mics, mic preamps and studio equipment.

These should not be used in reverb driver positions. Great for phase inverters and other positions.
