VERY scarce silver anode French Mazda 5751 tubes with triple mica, like the equally rare 12AX7S Mazda tubes, but with the lower gain of a 5751. Punchy, quiet, and very detailed with incredible dynamic range.

These are identical to the Bugleboy types, made in the same Holland factory at the same time. 1960s Heerlen, Holland (Bugleboy factory). This is a sweet sounding, long lived 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, 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. I’m not listening to recordings anymore. I now have live performances in my living room.
