Hi guys,
Anybody here has a copy of operating manual for Precision 660 tube tester? I would l love to get a copy. If anyone can let me know a link on the web to a .pdf file, that will be great too. Thanks in advance.

Here's one for $15.

Thanks! I found a couple of ftp sites that had the manual and tube datasheet for free download. I can now test all those old tubes that I scored last weekend.
