Dennis’ curve tracer is the more complete solution, but if you’re interested in the one on my blog its in the file section of TekScopes.

Hi Dan,
I can help you test tubes on your 575.

Like you I was very impressed with George Lydeck's (Glydeck) creativity and when a 575 fell into my lap for $20 it acted as a catalyst for me to build an adapter to test tubes. I went one step further than George: I came up with a way to test any tube on a 575, 576, 577, 7CT1N or 5CT1N.

You can read  about how you can do it in my paper which you can download at

If you want to get one of my adapter boards please contact me off list at dennis at ridesoft dot com.

Hi Brad,
Do you have or know anyone selling an adapter/fixture to match tubes on
a Tektronix 575?
Or, do you know if there is a schematic I can buy? Glydeck has a blog
about this, but there is no schematic or info to contact him.
