I think the 10MOhm/V figure of the basic VTVM was the figure to beat when they designed the FET-input (and subsequent) meters, and so they did. (Or at least meet it.) It's awfully hard to kill a vacuum tube, though, so I still like the VTVM when generally poking around. Mine's still on the original vacuum tube. We built it in what, about 1975? -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
