Pair of RCA 7581A power tubes. These tubes test NOS. The 7581A's share a lot in common with the 6L6GC and are rated for greater power dissipation at 35w instead of 30w. Internally these tubes are very similar. 7581's are great sounding vintage tubes that can be a great upgrade for your vintage amp or HiFi system designed to take the 7581A. We have some really great examples!
