RCA 6SN7-GTB Preamp Vacuum Tube
The NOS RCA 6SN7GTB vacuum tube is known for warm mids, smooth highs, and good bass. These are 1960's production preamp tubes that have black plates.
We have only a few available so matched pairs may not be possible, but balanced triodes is. If you need a single tube for your Schitt Lyr, Dark Voice 336SE, or deHavilland UltraVerve for example, these are for you!
Note: We have several variants on hand. Photo shown is not necessarily exactly what you may receive.

RCA 6SN7-GTB | Superb sound
by Ryan -
Excellent sounding tube, very good bass out of the box. Can't wait to see what this RCA-6SN7 sounds like after a couple months of burn in.
