These are 2 Sylvania 6BQ5/EL84 power tubes. One has a regular Sylvania box and shiny black plates. The other one has a large Sylvania box and black carbonized plates. They both date most likely to the late 1950's early 1960's. I tested each one on my calibrated Hickok 6000 tester. They both scored at 7000 M/hos, which is within the range for new tubes tested on this unit. Just $20.00 each plus shipping.
