Precision 660 Tube Tester Roll Chart Data needed for 2 tubes
11/24/2009 2:49:59 PMBob E
My roll chart is torn in the spot to read the data of
1U4 and 1U5
Can anyone provide me the tester settings for those 2 tubes?
Also is there somewhere that I can download that tube chart data? I am also missing the data before and after for about 6 tubes on either side of the 1U4 and
1U5. Maybe a few others too.

Bob,

There is a PDF of the chart data partway down the page.

Jeff,
Thank you so much! And thanks to the unknown folks who did the "heavy lifting" getting all that digitized!
