Tight current matched Pair RCA 6L6GC black plate tubes test NOS

Selling some of the best tubes from my personal collection. More to come, so keep an eye on my other listings or message me if you're looking for something specific.

Tight current matched NOS testing pair of RCA 6l6 GC black plate tubes. These are backups I've held onto for many years and sound fantastic. Beautiful sounding tubes- chimey cleans, rich and creamy breakup. These test new and have only a couple hours of use.
