6SN7GTB
Tall Bottle
Chrome Dome
Blue Dot Factory Select
Audio Tubes
NOS
All 4 of these tubes were made
in the U.S.A. by Sylvania and both were carefully tested in my Hickok Cardmatic tester. They will significantly improve
the sound quality of your amplifier. These all are the tall bottle, black triangle plates and chrome dome top.
These are rated among the best sounding American made 6SN7GTB tubes
ever made. They also have the desirable blue dot on them. They were
carefully selected at the factory for the best audio sound and higher
test results. If you need more of these rare tubes I have them.
These are getting scarce and are a high end tube used by most of the professionals. Great for guitar amps or any high end audio
amplifier. These tubes are what audiophile enthusiasts are looking
for. They can be used as driver tubes in your amplifier. The
tubes will come in new white 6SN7 boxes, as shown in
the photos. I will pack carefully & ship
very quickly.
Matching Sylvania codes on both tubes are: 863335
Test
results: 89/91, 89/91, 89/92 & 89/92, whereas a minimum
good is 50/50 on this Hickok Cardmatic tester. These are a matched quad.
Tubes 100% fully guaranteed!
