I used to work at Tek and took the opportunity to purchase this from Tek Surplus in 1978. See photo #12. I have used it on and off over the years and it has never quit. Now I have many other storage options and I have reluctantly decided to place this with someone who can use and appreciate it. The 7514 was the pinnacle of the original generation 7000 series. As I found out from it's project manager and my division engineering manager at the time it pushed design to the limit in two areas. The basic electrical and mechanical design was based on the 7504 which is a real boat-anchor. In order to supply the additional power for storage and to reduce weight, one of the first switching power supplies to appear in test and measurement equipment was designed. This was a nontrivial achievement in the late 60's. The resulting design with some modifications was used for all subsequent 7000 series mainframes. When combined with the goal to not degrade 7504 on-screen performance, elevated storage with split- screen capabilities and every storage function imagined at the time made electrical design difficult and CRT design nearly impossible. Lesson learned: future generations of Tek CRT storage did not try to serve all needs. So the 7514 is somewhat unique, was very expensive and had a relatively short life in production as Tek rushed to introduce second generation products which were cheaper to produce. No more gold circuit boards like those used in the 7514. There have been a few of these pop up on E-bay but none have approached the condition of this one. I completely calibrated it several years ago and checked it out just prior to listing. As you can see from the photos, storage works fine and non-store rise time is about 3ns with very clean transient response. Measured bandwidth was 108 mhz and would be more if the spec. on aberrations was pushed to the limit. Spot size, trace noise and writing rate are what one would expect. This comes with nine spare circuit boards from a 7504 which I scrapped years ago. They are identical to the ones used in the 7514. Also included is a camera mount and the thick original manual. I have a new and hard to find CRT for this currently listed on Ebay. S/N B020130. Just to be clear: NONE OF THE PLUG-INS SHOWN IN THE PHOTOS ARE PART OF THIS AUCTION. With the extras this is quite heavy and will be packaged carefully in a large box so shipping is expensive. The amount quoted is worst case to the West coast. If you are closer to 27013 it could be significantly less so wait to be invoiced for the correct amount before paying. I will ship to Canada but it will be expensive. I do not ship internationally.
