In Reply to: Those transmitter tubes posted by Frihed89 on December 5, 2006 at 00:26:41:
Frihed89,I always thought it was dangerous to mix extremely high current and water, but many transmitting tubes were/are water cooled- they have a water jacket around the base with inlet and outlet.
A friend gave me what is really a modest transmitting tube, marked as a Mazda. The tube appears to have never been used. It's a two pin- the pins are perhaps 12mm, envelope is about 50cm long and 10cm diameter- and air cooled. It interesting in that it doesn't have any kind of getter, there is a small handful of granular metal chips and I'm told this material soaks up any outgassing of the materials. It's very odd to have a tube with all this heavy, free grains in inside- it must be extremely non-conductive. There are also interesting manufacturing notations both inside and between the pins by several hands, suggesting a lot of hand work and individual testing.
It seems an attractive idea to build 4000W monoblock amplifers with a couple of tranmitting tubes. Besides the power, I imagine they're very linear and dynamic too, but imagine having to call the plumber when you need to move your amplifier to another room!
Cheers,
