--Bill Orr also had a water cooled setup of an RF amp for mobile work, anyone remember that? Water cooled tubes (designed to be) that used a fuel pump and a 5 gallon jug of water... Brett, In the 80's Panasonic started using an oil filled heat exchanger in their HIFI amps that replaced the normal Aluminum heatsinks and allowed a more compact chassis layout. Even a 5 year old laptop that I recently had to fix the power connector in had a similiar small oil filled assm. that allowed the internal fan to be placed in a better location. I suppose this type of cooling could also be used with the ceramic tubes alowwing thermostatic fan control and external radiator mounting. A smaller computer fan could then be used to further cool the other internal heatsources. Sorry about the formatting. AOL grabbed something from the former e-mail and won't let me change it.
