[sdiy] OT: Power cord for oscilloscope?

[IXQY at aol.com]

 Greetings all,
 I have an old Tektronix scope, Model 422 that has a power cord in 
bad...no..terrible condition. Does anyone know where I can buy a replacement? The round 
connector that fits on the back of the scope is about 1 1/16th" in diameter, 
and has female connections that look like this:

 I've email tech support at Tektronix, but had no help there (copied text is 
below).

 Thanks for any help,
 Andrew Sanchez
