Pair, National Union 6L6G Radio/Audio Amplifier Tubes, Strong On Amplitrex
Item History & Price
You are bidding on apair of used National Union type 6L6G audio output tubes. They are nearly identical tubes with the large G envelopes. They test strong on my Ampliflex AT1000tester. One tests with emission of 84% Emand Gm of 91%, while the other tests at 80% Em and 81% Gm. So both test strong, with fairly high grid emission. They are not quite identical as one has a date code of EN, and the other AC. I noticed on one that the very top black metal "...U" above the mica top support is loose, but falls right back into place. I have never seen this before, and it should not affect the performance of the tube. Theyare guaranteed to make a nice pair and sound good in your amp! Shipping weight is 13 ounces. Please see my other auctions for moreinteresting radio items and tubes.
