This listing is for 28 brand new old stock in original box never used tubes.  4 of the boxes are a bit rough but the rest are nice. There is a mixture of 2 different letter and box types shown in picture but all are RCA. These are a super delicious sounding tube and will drop in replace 6V6 types IF and only IF the filament power supply can handle a 20% increase in current draw.  6V6's typically can draw 500ma (1/2 amp) and these draw 600ma.  In most cases you should be OK but you want to check.  I assume absolutely no liability for these tubes actions.

I have had great luck putting them in my Magnavox and DIY amps and enjoy not having to pay "mystical" prices to the hoarders for unmolested USA grey plate tubes.  These are sold as is with no warranty but  have been tested by me in actual amplifiers and in my trusty Dynajet tester.  These have not been through the "flipper mill".  I found 60 of these in an old storeroom and tend to want to keep the rest but i'm open to discussion if you need more than 28. I have a shit ton of lovely 6V6's too.
