I have for sale a Vintage Western Electric 310A tube. Earlier fine mesh version. Fully tested tube on AVO MKIV New tube tests 5.5ma 1.8 mA/V This tests 5.5ma 1.2 mA/V So plenty of life in this one - no shorts etc Tube Testing: Unless stated new old stock all tubes are used. I test all tubes for shorts, filament and emission. All my testers including AVO MK IV , Lafayette etc are vintage, and I have not had them calibrated in decades. For this reason I no longer list the emission readings of tubes as they would not be precise. The AVO MK IV still to this day is regarded as one of the best tube testers ever made. I personally think the AVO MKIV is the best for testing most tubes with the exceptions of 12ax7 and ECC88 etc which I feel the results are accurate but not precise. I only list good testing tubes and have been around tubes for many years and as always stand by every tube I sell and have excellent feedback I PACK ALL TUBES VERY WELL FOR SAFE TRAVEL AS REFLECTED IN FEEDBACK.No longer post to China as I will not declare lower value for customs as it is illegal to do soUnless stated New Old Stock all tubes are used I NO LONGER POST ITEMS TO ITALY, GREECE, RUSSIA , MEXICO ETC DUE TO POSTAGE DELAYS For buyers in Europe and parts of Asia that have high import duties, please remember I do not falsify customs forms so please be aware of your own regulations.
