[Test-Equipment] late HP 428B current probe manual

[pete wokoun, sr.]

I have a later version tech manual for the HP 428B (units that have the 
printed circuit boards, manual part number 00428-90004 dated Sept 1974, for 
serial numbers 0995A and above) all scanned and converted to a 15,626 KB 
.pdf file.  It also has an appendix that covers the earlier models.  I was 
going to upload it to the BAMA site but now have read there where they don't 
want any more test equipment.   Soooooo, anyone want a copy?  Will email it 
direct to anyone who wants it as an attachment.  Just make sure your 
provider allows attachments that large.

aloha, pete KH6GRT
