Hi, Not as old as some. Anyhow it did not perform as well as I would like so it is dead. My various designs using pentodes had better sound and fewer issues. I made four, one SE, one P-P with small triodes and two with 6AS7s. None could match the sound quality of the pentode ones. All needed a lot more gain and drive and put out less sound.
