Glass DC and sealed RF metal tubes are both sold as CO2. Ask the tube maker, rated or peak watts, and a power meter reading before packing.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.
