We’ve cleared out all of our remaining decade resistors and capacitors, and they are now available on our Resistors and Capacitors pages, as well as being on the Recently Added page.
This equipment has been significantly marked down and you will not be able to find these pieces at these prices anywhere else.
It seems we have more stuff than we thought. Disposing of all the electronic equipment and parts will take at least until mid 2025. We will be updating our web site regularly with new items for limited times. Do keep in touch and let us know what you might be able to use.

This is a list, including prices, of all the equipment we have in stock that has been verified and tested as OK by Walter II prior to his passing. This means that this equipment received an inspection by him, and has an “OK” sticker (unless otherwise indicated in the price list).
We will continue updating our online inventory with this equipment, but you can get a head start on it now!
We are also discounting all of our Parts in Tubes by 50% – which will end on 31 October, 2024! These parts will disappear forever after that.
Until the end of November, all of our Tektronix 500 series mainframes are on sale, at the end of that these frames will no longer be available. Conditions of these frames vary, but we are treating all of the base frames as “parts” units.
Prices and current stock levels are as follows:
We do have certain 500 series frames listed that have modules in them, and we will be adding more to the site in the near future.
