This is auction is for 2 tubes. Bid once, get both tubes shown.
These are the most sought after 6L6 type tube ever. They are made by Western Electric, branded National Union. They are according to all information I've seen, absolutely identical. They have collector value, but not the sky high pricing of Western Electric labeled examples. If you want to actually use these in an amp and save thousands compared to W.E., these are the ones to buy.... But you probably already know that if you clicked on this auction. They may not work in every 6L6 circuit, please do your homework and consult with the manufacturer or a tech if you are unsure. I used to use this type in McIntosh Mc30 and an Ampeg B15N with stellar results. A friend of mine has been using the same 4 in his Mc30 for over 20 years.
This pair of tubes exceeds the new specs on the Western Electric data sheet. The values and test methods are shown in the last 2 photos. The tubes offered in this listing are numbers 35 and 51. Flashing is intact, bases are firm and tight, pins are straight. Will be packed very securely - they would fit in a small flat rate box, but not with enough room for me to feel comfortable with these rare and irreplaceable tube. Medium Flat Rate or my packaging will be offered to international buyers. Shipping is free within the US. If you need them by a specific date, please message me and I will accommodate you.
International shipments - if you choose to use eBay's shipping service, there is a limit of $100 against loss of the items in shipping. If you choose this and the tubes are lost, I will only refund you the amount I recover from their limited insurance. I will insure shipments through the USPS for the full purchase price, and I recommend this highly.
I also have a single tube with a loose base (number 48) that I am offering in a separate listing. If you buy all 3 together, I will combine shipping - simply complete the payments and I will refund you the shipping. Or, I can invoice you with the adjusted cost once you've won.
International buyers - please do not ask me to falsify customs forms with a lower value. I won't do so under any circumstance. Please save both our time and don't bid if that's part of the agreement you expect. Thanks!!
