One closely matched pair of 6L6WGB tubes, by Sylvania.
The prints on the bases are off due to age, some print left on the glass tubes to indicate that they were by Sylvania.
Among the best 6L6GB tubes available for guitar amps, and any amps that call for 6L6GB tubes, such as McIntosh MC30.
Test Ratings: 95 and 98 on my Jackson 648s tester, minimum is 70, new tubes at 105.
