Here we have 5 POSIBLE N.O.S. 6C4/6135 G.E. 5 STAR INDUSTRIAL TUBES TESTED AT #1 700 #2 720 #3 740 #4 740 #5 720  I Guarantee you will receive what is pictured. Tested on my rebuilt & calibrated EICO 625 Emissions tube tester. 550 is the lowest Test & 1k is top notch. It tests each pin - part of the tube separately for shorts and tube life. Your testers may have different readings than what I have & that I can not control. I am not A tube dealer just thinning out my collection of many years. I have repaired, built, tube amps, radios, audio amps & other equipment for over 25 YEARS ! The items listed are used ( Sometimes are unused old stock ) But they are SOLD AS IS ! No Returns, No Refunds ! Because of tube swaps, Scams, Tubes Used on damaged equipment, & other problems that tube sellers have. I read & see it ALL the time & it is A shame.

Please ask any & all questions before bidding or buying.  If A problem should happen PLEASE Talk to me. I do not sell junk. If it has a loose bottom, Loose top cap, burn marks, Or even tests weak ( but some say its still good ) ECT. I THROW IT OUT !! You will get what is pictured & the test results from my tester.

Please look at the pictures, They are most of the description !
