Hi Craig,
You can easily build one in just a few hours. The only challenge is obtaining the right tunnel diode (eBay), mounting it (use conductive epoxy), and confirming the rise time is within spec (I borrowed a high speed scope from my work for this). The other parts are garden varieties obtainable from Digikey.
I built two of them but sold the second on eBay.
There was a great posting by one of our members, Sergey, on this. I don¡¯t have the details handy where I¡¯m at but if you are interested in going this route I¡¯ll look them up and send them to you.

Looking for a working condition Tektronix 067-0681-01 Tunnel Diode Pulser for doing the Cal 6 on a 2400 series scope. I have all other tools but am missing this tool to complete the full calibration sequence. Please reply to electronixtoolbox@...
if you can help.
My background is 42 years working in the HVAC industry. But I have had the hobby for about 25 years learning about and repairing Tektronix scopes. Not an expert just have some experience of a lot of trial and error getting them working. I started with the 475 model and with a manual and advise from Reed D. Learned how to navigate thru the Tek manuals and have been somewhat successful at repairs. Since then I went to the T900, 455, 465, 2430/A, THS700, 222 and onto the 2400 series. Which now I mainly deal with the 465 and 2465b,2467B scopes. Over time I¡¯ve acquired TG501,PG506,SG504,SG503. Several that are non working and still don¡¯t work today and some that are fully working. I seem to not have the knack of fixing plug-ins.
I have many scopes that I need to repair in my shop. I just hate to see them parted out or thrown away when the majority can be fixed with a fair amount of time and effort. I¡¯m not retired yet but hope to be soon so I then can spend more time with the units in my shop.
If you have made it this far in this note. Thanks for reading and ask any questions you have.
