A nice tube that is identical to the Bugleboy tubes listed above, and were made in the same factory. These all have Heerlen, Holland early date codes, 4 seams in the top glass, large O top getter rings, and most with the old style white label. These were industrial stock and some were made for many different brands of amplifiers, with various labels, but many are Philips Miniwatt. The early large halo getter 12AX7 is a really fine and sweet NOS Dutch tube.

Getting rare 1950s date coded BugleBoy type tubes made in Holland. These are the early Holland types, long plate version with the rare foil strip D-getter. These tubes have nearly vanished from circulation. The sweet sounding essence of the Bugle Boy type, but with improved dynamics, top end, detail, airy and tight bass. These tubes do something that just makes all the instruments so real. I could swear the instruments are in the room with me. Iím not listening to recordings anymore. I now have live performances in my living room.
