  Tektronix 3 Ring Binder
Binder These Tektronix 3 ring loose-leaf binders are sold in pairs; one 2 inch and one 1 inch. Both sizes are dark blue with the Tek logo in silver on the front. They have been used but are in excellent condition. These are great for holding your miscellaneous Tektronix publications.
Price: $5.00 per package of two
  Tunnel Diodes
Tunnel Diodes These new Tektronix (152-0125-00) 4.7ma Tunnel Diodes have had their leads clipped and bent for installation in a circuit board, but they were never installed. Both leads are about 3/8" long and can be easily straightened and lengthened to fit your instrument. Here is a partial list of the Tek instruments these go into: 1L40, 1S1, 1S2, 11B1, 11B2, 11B2A, 147A, 1470, 148, 21A (new style 555 Timebase), 22A, 3B4, 3B5, 408, 432, 434, 453, 453A, 454, 466, 491, 5T3, 544, 546, 547, 556, 7B70, 7B71, 7D11. A very similar diode (152-0125-01) was used in the following: 335, 464, 465B, 466. The 152-0125-00 would probably work in place of the -01 version of the same part, however, I have not actually tried it. To be certain your instrument uses the 152-0125-00, you should check the service manual for your instrument. I know these are good diodes since I checked them on my 575 Transistor Curve Tracer. (Tunnel Diodes cannot be checked like an ordinary silicon or germanium diode since they will look like short circuit on an ordinary ohm meter.) Tunnel Diodes are getting hard to find these days and you might want to consider putting these away for a rainy day, just in case . . .
