Chinese Killers  Time owned: 0 to 3 months
The Russian 811A called G811 are far superior to Chinese 811A tubes. Although the plate structure us rated by size 65 watts, like Chinese tubes the rating is closer to 55 watts. A true 65 watt plate 811A is made by GE or RCA with the plate fins.

These Russian tubes are properly made with high vacuum and a carbon coated thorium tungsten filament.

The Chinese 811A tubes that are reported to last 1500 hours by some may be missing the carbon coated filament that greatly reduces filament life.

The carbonization process is a more costly and adds another step and longer evacuation time. The Chinese have a bad habit at times and will do anything to save a dollar and unfortunately 'toss you under the bus'.

So, buy the Russian 811A for your ham radio amplifiers. You do not have to suffer with an inferior product. These are available on ebay.
