Lightly used, tests as new.

Labeled and boxed as Sylvania and GE. 7 "notches" in the plates. The following are all manufactured by the Mullard tube company in England. All (except for the earlier production Large Base version) are IDENTICAL. All bear the famous "center hole in the guidepin", same production codes, and exceptional Mullard quality which is second to none. These typically last decades as compared with modern production GZ34/5AR4s which last hours to a couple of years (if you're lucky).

Excellent quality, cost effective tubes by Matsushita. MUCH higher quality and longevity than any of the modern production GZ34/5AR4s. Highly recommended. Labeled and boxed as RCA.
