Update 5/18/25: Shipping

UPDATE 5/18/25

An error occurred during a recent product list upload, which required temporarily disabling the store and reuploading of products. This action is now complete.

UPDATE 5/12/25:

In addition to Tek prefix 151, prefix items 152, 153 and 155 have now been inventoried, priced and added to the site.

Tektronix parts are being added to the site. HP parts will follow once all of the Tektronix parts have been inventoried and priced. This process is long, dull, boring, but necessary.

Currently, the transistors with Tektronix prefix 151 have been inventoried and priced, and are ready for purchase either directly on the site or by contacting me at tom@tekandhpparts.com.

I have made reasonable efforts to have accurate descriptions of the parts, but the sources may not be completely accurate. Please use any information on the site as “information only”. The inventory is a mix of individually Tektronix packaged parts, bulk Tektronix packaged parts and bulk parts matching Tek’s cross reference descriptions. Getting this level of detail and pictures on the site is on the “to do” list, but for now, we are concentrating on getting quantities and prices done first. If it is important to you to have clearly branded Tektronix components, please inquire by email first, and I will let you know the branding status.

Items with non-zero “On Hand” quantities have been inventoried and may be purchased through the site.

Items with zero “On Hand” quantities have not yet been inventoried or priced. This does not mean we are out of stock on these items, so if you need one of these parts or more, please contact me directly via email tom@tekandhpparts.com.

Lastly, if you do not see a Tek item listed, we may still have it available. To inquire, please contact me directly at tom@tekandhpparts.com.

Update 4/1/25

Over the next two weeks, we will be transporting Sphere’s Tek and HP parts to our location in Washington. Once they are physically in our possession, we will be able to fulfill any requests you may have for parts from our inventory.  If you have an immediate need, please feel free to contact us at tom@tekandhpparts.com. 

We are honored to continue to provide access to the vintage Tektronix and Hewlett Packard parts inventory from Sphere Research, Inc.

Thank you for your patience in this transition. We look forward to continuing a small portion of Sphere’s history of serving the Tektronix and Hewlett Packard test equipment community.
