I have an old Lafayette portable tube tester (I think it's model TE-21 but I don't remember offhand; probably not important) and I'm curious about the meaning of notation on the tube data paper scroll. The tester has 10 switches, each of which may be set "up", "down", or left in the center position. Per-tube data on the scroll indicates which switches should be set "up" and which "down". I assume all the others should be placed in the center position. The question is this: some of the numbers indicated on the scroll for "up" or "down" for some tubes are printed in bold type (most are in regular type). What does bold type indicate? Replies directly to me, please. Thanks. -- -------------------------------------------------------------------------- Aaron Endelman KK6QH endelman@eng.sun.com SPARCworks IBEx Group UMTV12-33, Sun Microsystems, Inc., 2550 Garcia Ave., Mtn.
