Item Description:

I bought these tubes a few months ago as NOS, see below:

I used them in a Decware Mini-Torii, a 3.3-watt amp, for a few hundred hours.

The 12AU7 tubes only become warm, not hot, in the Decware amp (thus, low stress on the tubes).

I sent these tubes to Brent Jessee Recording for ADDITIONAL testing, Brent confirmed that they are a MATCHED PAIR and near to NOS in use (within 75% of being NOS): Valvo 12AU7 68-65 and 69-69. This would be about 75% or so of new.

This is a quiet very nice perfect matched set that is priced to sell.
