I have an IT-17 and also a IT-3117; don't believe I have ever run into an issue using these units with any tube types I've tested. Don't have a 6SN7 or anything which uses one. Can't be a software glich. Maybe something specific to the tube....meaning a bad tube. Can't believe Heath engineers would single out one tube as a issue. Course maybe the tube charts are wrong. Just guesses. Yes, there are still some who have tubes and do use tube testers occasionally.</span></div><div id="yui_3_16_0_1_1455924211761_12072"><br><span id="yui_3_16_0_1_1455924211761_11857"></span></div><div id="yui_3_16_0_1_1455924211761_12084"><span id="yui_3_16_0_1_1455924211761_11857">73, Larry KC8JX</span></div><div id="yui_3_16_0_1_1455924211761_12085" dir="ltr"><span id="yui_3_16_0_1_1455924211761_11857">'one of the x-hams at Heath'</span></div><div id="yui_3_16_0_1_1455924211761_11719" class="qtdSeparateBR"><br><br></div><div style="display: block;" id="yui_3_16_0_1_1455924211761_11723" class="yahoo_quoted"> <div id="yui_3_16_0_1_1455924211761_11722" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_1_1455924211761_11721" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_1_1455924211761_11720" dir="ltr"> <font id="yui_3_16_0_1_1455924211761_11724" face="Arial" size="2"> <hr id="yui_3_16_0_1_1455924211761_11733" size="1"> <b><span style="font-weight:bold;">From:</span></b> Terry Perdue <k8tp@comcast.net><br> <b><span style="font-weight: bold;">To:</span></b> heath@puck.nether.net <br> <b><span style="font-weight: bold;">Sent:</span></b> Friday, February 19, 2016 5:07 PM<br> <b id="yui_3_16_0_1_1455924211761_12091"><span id="yui_3_16_0_1_1455924211761_12090" style="font-weight: bold;">Subject:</span></b> [Heath] IT-17 Tube Tester question<br> </font> </div> <div id="yui_3_16_0_1_1455924211761_11832" class="y_msg_container"><br>Does anyone recall having a problem testing 6SN7 tubes? I've tested a number of them, and the meter always pegs violently using the listed settings. I've noticed that changing the 'Type' setting to 1 (the chart says to use 2), gives an in-scale reading. But I have a later loose-leaf listing that was compiled after the roll-chart was produced, listing many new tubes that aren't on the roll, and it still shows type 2 for this tube.<br><br>Any comments? Other types found that don't test properly using the listed settings? Or maybe no one uses tube gear anymore...<br>_______________________________________________<br>Heath mailing list<br><a ymailto="mailto:Heath@puck.nether.net" href="mailto:Heath@puck.nether.net">Heath@puck.nether.net</a><br><a href="https://puck.nether.net/mailman/listinfo/heath" target="_blank">https://puck.nether.net/mailman/listinfo/heath</a><br><br><br></div> </div> </div> </div></div></body></html>
