Hi Guys

These tubes are getting extremely rare.

As you probably already know, they have identical specs to the 6SN7s and in this case, the same gorgeous sound as the holy grail Tung Sols, with what is often perceived as added 'space/air'. Though not cheap, they are about a third of what is now being asked for the TS 6SN7. All you need are 2 easily sourced adapters.

They are immaculate, matched tubes, test NOS on my AVO 160CT, and come in their original boxes. If your after the best all round 6SN7 IMO-bar, perhaps, the Sylvania 6SN7W metal base- look no further than these. £195 + £5 postage
