Sold: *price drop* Cetron 7236 tube.

Many consider the 7236 power tube an upgrade for OTL headphone amps that use the 6080 (6AS7), like the Bottlehead Crack. I bought this tube NOS. No measurements, but I listened to it for a couple of hours in a Crack with Speedball and it sounded great. Sold the Crack a while back so time to sell this tube.
Original box, tight base, 8051 date code (December 1980). Price includes PayPal and shipping, U.S. sale only.
