Matched quad of Philips/Sylvania 7581A’s. No way to test them but they were purchased here as ANOS. They look fairly new so I’m guessing low hours. Each have shiny “dental mirror” flashing and most of the lettering in tact. These have twin disc getters. Great tubes if clean headroom and punchy bass is desired. I was going to use them in my Twinplex but decided to go with GE’s instead. No trades.
