Lot of three vintage 6AK5 sharp-cutoff pentode vacuum tubes, each in a box: an RCA Radiotron box hand-marked 6AK5, a GE "Electronic Tube" box printed 6AK5/EF95, and a plain white box hand-marked 6AK5 and N 5654 holding a Westinghouse 6AK5W (glass printed 6AK5W, Made in U.S.A., Westinghouse). Untested; sold as found. Boxes show handwriting, edge wear and some scuffing.

The 6AK5 / EF95 / 5654 family is a 7-pin miniature pentode used in RF stages, test gear, ham radio and DIY audio and preamp builds. The 6AK5W is the ruggedized version.

Please see all photos for the boxes and the tube shown.
