Product details
New vintage Soviet 6N9S Double Triode tubes.
Four tubes in one lot.
Same date tubes in one lot (1 or 2 tubes in the quad may have slightly different months).
If you buy several lots, different batches may have different dates.
All tubes are in their original boxes.
These tubes are not tested, because our experience has shown that when the tubes are from the same production batch, they have close parameters. Therefore, there is no point in testing them. We simply open them and inspect them for mechanical damage.
The tubes look great and are in excellent condition, but I ask buyers to take into account the fact that in most packages for tubes, the metal brackets are completely rusted and falling apart.
