RARE PAIR of RCA 6L6GC BLACK plate "OO" Holy Grail tubes with the same 1975 date code!

These hard to find tubes are in excellent condition with light use, test STRONG and Perfectly MATCHED at 103%/103% in mutual conductance and less than 3mA apart in current! Beautiful sounding and looking tubes with dual "OO" getter and near full bright silver flashing in really nice condition... it doesn't get much better!

We've auditioned these in our both of our amps and these both perform perfectly... a sweet well balanced clean sound with sparkling detail, a smooth bass and of course that wonderful vintage RCA TONE!

You'll wake up your amp with these fine sounding vintage tubes! Truly remarkable sounding tubes... the way they should sound (WAY better than Chinese or Russian tubes). Treat yourself, you'll be glad you did!
