Thanks for posting the B&K 501A.  I looked it up and found this, looks like a good product and educational demo.

Makes me want to sell my 575, and get one of those. Probably not anywhere near the capabilities of the 575.

And the tubes warm the basement.

Deas anyone have the schematics for the ELV Curve Tracer KS7000?

Thanks in advance :-)

Completely scrapped the pcb. for space reasons and rebuilt this:

I have three curve tracers...I have one Type 575 Mod 122C that is in perfect working order, another nearly identical one that isn't in good working order (repair queue, eventually), and a 577M1 with working storage. Pictured here is my experiment at rejuvenating a set of tired Burroughs Nixie tubes that came out of an -hp- 3440A voltmeter (also in repair queue, mainly for the plug in now). It actually worked very well, and the curve tracer provides excellent visual feedback of when the rejuvenation is getting there...the negative resistance region goes from being absolutely crazy to rock stable (and of course the poisoned bit of cathode is now lighting properly). I need to designed a test jig with proper sockets for Nixies to make the process less manual.

Also, I *highly* recommend anyone who owns a curve tracer find a copy of the Tektronix Measurement Concepts book on semiconductor devices.
