You are bidding on (1) NOS GE 35W4 electron tube, made in the USA in 1978.  Identical date codes of CM indicate January 1978.  Gray plates, dual mica spacers, and top mounted round halo getter.  Tubes come from a sealed case of 100; tubes are industrial packed and therefore have a white box with 35W4 on the top of the box.  Tubes ship in original individual industrial tube boxes as shown in the photos.  These are the exact same tubes that were also sold in the retail orange/gray boxes.  Note your bid is for one tube, not the case. 


All our tubes are tested and guaranteed by us; we only test tubes on one of our quality calibrated mutual conductance testers, NEVER on an emissions tester.  The tester we use is a computerized cardmatic tester from Tubesontheweb dot com; the specific model is a Western Electric KS-15874-L2 which was made for Western Electric by Hickok.  Our backup tester which we use occasionally is a military TV-10D/U.  For specialized tests, we employ one of our VTV Dual Triode Characterizers (for preamp tubes) as well as a Maxi-Matcher (for power tube matching).  Tubes are guaranteed for 90 days, refund or replacement our choice. Thanks for looking at our auction and be sure to check out our other auctions for other tubes that may be of interest.  Buyer pays shipping. (lot VX-35W4)
