It's EIMAC, and it's good! Time Owned: more than 12 months.
You get what you pay for, so for long life and trouble free operation, buy EIMAC. I use this tube, or a variant in my 1/3kW 6 meter repeater. Quality manufacturing and a concern for the customer are tops at EIMAC. I would not trust a Chinese or Russian tube in my amplifier that is impossible to get parts for. Remember to drop you heater voltage a bit, keep it cool, and watch your plate and gird dissipation and you'll be fine. When my current tube goes flat, I'll report on the hours of service. It is on 24/7 and I have an hour meter on the station.
