The indicated twin triodes tubes from a sealed big box, I ask 5usd per 1pcs.
All tubes have been roughly tested at 0V grids bias, at least plate currents of the halfs can be compared and corresponding tubes selected.
Cost of the air post to USA is 8 usd if up to 0,25kg parcel weight, 14usd if up to 0,5kg, 24usd if up to 1kg. Please ask if there are some more questions.

To mbrennwa :
Enclosed are photos of the selected 20pcs of 6N6P tubes. Each tube is marked by its specific number, visible on one photo, and other photo shows that all tubes are the same 1984 year, months I and II.
The third picture is the table of the tubes measurements. The first column is tube's specific number, second and third columns are the measured plate currents of the halfs at 90V plate voltage (grid bias is 0V). Hope this info explaines that all tubes are quite close to each other.
