Description: Sylvania 6L6GA Vacuum Tubes For sale I have a trio of Sylvania JAN 6L6GA that are superb. Notice I am testing transconductance at 250 and 325 plate volts and current draw at 325 plate volts. Tubes carefully tested for transconductance, current draw, shorts, gas, life and leakage. No tube is sold that has any gas, leakage or fails life and strength tests. Photo is of the actual tubes on auction. I take a great deal of pride in the honesty of my representation and the quality of my customer service. There will be no unwelcome surprises with my tubes....guaranteed. Test Results:4200, 3800 and 4200 gm (Triplett 3444)27.0/2.57, 21.0/2.32 and 33.3/2.71 ma/gm (Maxi Matcher) Minimum:2400 gm (Triplett 3444) Test Equipment: Hickok 539C w/ Fluke 73III multimeter Triplett 3444 Hickok KS-15874-L2 Cardmatic Maxi Matcher w/ Sola CVS Regulated Power Supply The Hickok 539C is a highly regarded transconductance tester. The Triplett 3444 is one of the finest testers ever made. Exceptional in every aspect. Superb with directly heated triodes. The Hickok KS 15874-L2 is a commercial version of the wonderful 118 Cardmatic. In my opinion, and the opinion of many tester experts, this is the best tester that was made by Hickok. A real gem. The Maxi-Matcher is a useful tester for measuring current draw and transconductance at 325/400 plate volts with 5 bias voltage settings. Very good with 6V6s and EL84s, this tester falls a bit short of true operating levels on 6550s, EL34s, 5881s and 7027s. Still much better than most "suitcase" testers for measuring power pentodes. I do not trust the minimums on this tester and they are therefore not listed. The industry standard by default. ALL of my testers (except Maxi) have been calibrated and redone by Chris Haedt. ===== Fully Guaranteed! ===== Money back on these tubes if they do not operate and test as described!
