Obtaining good tubes of this type is always a gamble if you use some of the online auction houses or off-shore dealers. I prefer to deal with shops located in CONUS. As with all ceramic tubes, you need to getter them (heater voltage only + ventilation) for 24 hours. The tubes are for my QRO HF-2500DX amplifier. I am getting at least 1500W with 30W input on 80m.
