PhilipsECG 6973 Tube USA Blue Label #2

For sale this is 2 of 3 USA made PhilipsECG power beam pentodes that have come into our inventory. This is one of the blue-inked examples, which puts it into the 1980s window according to this writer's understanding of information available on the web. Pictures include readings from each individual tube taken with a Sencore TC162 tube tester. Pics are in the order of emissions, emissions under life test, and leakage after a twenty minute warm up. Pins look good, a few smudges on the tube labels. 

These originally came to us as NOS, and we're calling them used, excellent condition based on appearance and test results. Glass on all three has a code of BR, with ACO below that.
