As for liquid cooling of the speakers, I was thinking about just immersing them in seawater. There is plenty nearby, and the possibility of the speaker changing the temperature of that 'heatsink' is fairly remote...

And perhaps you could play some Hendrix for the propellerheads running the SOSUS nets...

I've read recent postings about liquid cooling of Pass DIY amps.

My next door neighbors--Wilbur and Orville Wong--recently developed a liquid helium (H3) cryostat cooling system for the F5 Turbo V3. It works at 0.365 degrees Kelvin--and thanks to superconductivity, is 132.78% efficient. Working in their garage workshop (picture shown) they developed the cooling system for $3.23 (US) using parts from a Maytag washing machine, Yugo station wagon, and a Mercury outboard motor.

The picture shows the obvious jubilation of Wilbur and Orville, right after they measured the Turbo V3's output at 3.446 KW into 0.2 ohms. Wilbur found no problem in holding Orville's hand to the heatsink for more than a minute--although Orville subsequently lost several layers of skin and suffered severe hypothermia in attempting to remove his hand afterwards.

Ohhhh..... There is something so wright about their concept, and yet something so wong in their execution.

Enjoy....... Pass DIY and Class A forever.....!
Yes but how are they at bike repair ?

You got me thinking about liquid cooling my F5T now.. How about lead-bismuth like an old Soviet-era submarine reactor

And here I thought that everyone wanted Class A without all the exotic cooling because they used it to heat their houses in the winter. Heck, I would just add a slow and low fan just for circulation and keep the chassis BIG.

Sneak Peek - If my little BA-3 experiment works out as hoped, you can just pipe it into your central air ducts and heat the whole d*mn house - or get some very long speaker cables and move it around to the coldest spot in your castle !!!

As expected, please ignore what I said at post #2220 (Cal's Rule: "Never post an end date to a project"). Probably have another full week before I'm making any "cool music".
