Saw this and thought it snakeoiley/curious?

What do you think?

Quote:
The vacuum tubes that are used for tube amplifiers or guitar amps play an important role to amplify musical signals and drive speakers. The vacuum tubes are fighting against invisible enemies such as heat and vibration of plates. The heat and vibration that are always generated by tubes hamper music reproduction.

When KRYNA’s TubeRadiator is wrapped around a vacuum tube, it releases the heat accumulated in the tube to the outside. This new type of TubeRadiator is made of bronze containing phosphorus that is excellent in spring characteristics and strength. The corrugated form adheres to vacuum tube and demonstrates high radiating effect. By increasing the radiating effect the temperature of the surface of vacuum tube decreases, resulting in less thermal noise and a clearer sound.

Lowering the temperature of the vacuum tube's surface also increases the life expectancy of the tube. Test results of measured plate vibration in a tube indicates the effect of controlling low-frequency vibrations related to high-order harmonic and the power supply. Furthermore, bronze containing phosphorus has a characteristic of absorbing electromagnetic wave. Therefore, the this tube cooler also plays a role of filtering noise as it prevents the external impact on the tube.

If heat and vibration "hampers tone", yet I like the sound of my amp the way it is (not to mention the recorded and live sounds of my favorite players), why would I want to do anything that would "improve" (read: CHANGE) that?

Because graphs, obviously.

Think of how much BETTER Jimi and SRV could have sounded and played with these radiators?!

This sounds like snake oil BS.

At best there might be truth to that longevity claim if it can be scientifically proven.

But I have about as much concern over tube life as I do the lamps in my plasma tv.

This picture means nothing. It's like putting a fireguard in front of a fire.
TBH, if your tube sockets are soldered to a PCB then IMHO increasing the mass the PCB is supporting by sticking a phosphor-bronze heatsink on it is likely to reduce the reliability. I want to think it makes sense, like heatsinks on transistors, but I don't see that it does.

Valves need to maintain a steady operating temperature to work properly, don't they? I don't see why a well-ventilated amp casing can't do that job already. If they're overheating, there's something wrong with the design of the amp.

There *are* certain amps with overheating issues - my old DSL401 for example - but those problems are generally centred around excess heat being transferred through the valve bases to the PCB itself (a flaw in the amp's design). Heat sinks can help there, but you'd stick the heat sink somewhere other than on the valve bulb, because the problematic heat is the heat that's being conducted down through the valve base, not up and out.

tl;dr version: heat dissipation can be an issue, but an after-market heat sink around the valve bulb isn't the best way to solve it. I call bullshit on this idea!

I was searching for a demo of the Fucking Fucker and somehow found this. What the fuck? (NSFW)

THEY'RE A HUNDRED FUCKING DOLLARS?!?! I could probably make something similar with 10 bucks at Lowes..

Or just cut a cartridge oil filter and you have the same thing.

Also, that's dumb. I can imagine drinking guitar amp valves might be easier with one of those though. Makes my hot chocolate from Starbucks easier to hold anyway.
