Nice Matched Pair of Used GE 6L6GC "OO" getter tubes labeled RCA 1979
These are very clean, fully tested and auditioned tubes. Nice strong test results, closely matched 105%/108% Gm dynamic mutual conductance and about 5mA apart in current draw when played in our amps.
Biased up nicely and auditioned in both our p/p guitar and single ended stereo amps and these tubes test and sound awesome in both amps! GE 6l6gc power tubes
have wonderful detail and a sweet vintage GE TONE you can't get from tubes made today in China or Russia. Vintage GE tubes sound WAY better and outlasts them up to 5 times longer too!
You can safely use these in any 6L6 type amp that calls for 6L6, 6L6G, 6L6GB, 6L6GC, 7581 and KT66 tubes with no mods needed.
