These may or may not be used, but since we're not 100% sure we're selling them as used. ANOS = Almost NOS, tests as new. Black plates, white numbering. No labels or brand markings.
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.
Hi Mike, .....
NOS in original boxes. Some labeled as National.
