The LED is to show the tube is warmed up. But yes, the white strong ligth is boring.

You don't need the light to know the tube is warmed up, there is a switch that is audible with no headphones on.

Chinese socket  savers are block the light and haven't effect to sound quality.

It's simple and easy solution for blocking light and easy tube rolling.

Like this:

TubeMonger Socket Savers do the same thing which I said on the previous page.  Some of us would rather spend the extra cash for quality made non Chinese parts that are known to wobble in the socket.

I think the LED is actually time based. It will light after a certain amount of time (30 seconds, I think?), and I don't think it's triggered by temperature (which it should be, considering the function)

 

I came into this conclusion by observing:

- turning the unit off, then immediately on again. The tube, and even the unit is still hot, but the LED doesn't light up, and no sound comes out. I guess it's set as 'every time it's turned on, it must wait for certain time, before operational'

 

- switching the input to 'line' (doesn't use the tube DAC part), take off the tube, the LED will still light up.

 

It maybe their alternative way of implementing a LED that tells that the tube is ready. Maybe a time-based circuit is less expensive, or less complicated than a temperature-based circuit? I don't know.

Seriously guys its in the manual. It says the light will turn on to signal that the tube buffer has started to work. It tells you when the tube buffer DAC starts to work, since the line in didn't go through the tube buffer it won't wait until light is on to work. That's why you hear no sound until the light is on.

Or it's just a fancy/crappy chinese eye-candy.

Yeah, that's the LED's original function, I think. Problem is, instead of being triggered by temperature of the tube (as should be), it's triggered by a time range. Not much different, I guess, still serve the same aim.

 

When I say 'set to line, the LED still light up', I pointed that the LED's operational is not dependent on the tube (again, as it should be)

I have the black T1 and was sticking a cross of electrical tape over the socket and under the peg holes to block the light. Every time I tried a new tube the tape would pull up though and I'd have to do it again. Now I just stick the tape in a cross over the socket and holes. Hardly noticeable with the black on black unless you're shining a light on it. Faint glow of the tube, no white light.

Well at first I loved the freshness of the white light when I bought it. It's indeed a indication when the internal relay is switched on and the DAC is working with the tube.. You even hear it switch the relay.

 

After searching info about Tube amp technology I got seduced with the warm glow it give all trough with this kind of tube we only see the top filament glowing to produce heat.

 

When I saw the post from Salvatore on page 135 about "Led color mod by ElBartoMe"  I went crazy haha.

 

You know sometimes it's damn handy to have a woman in your life. They love Nail Polish and have almost every color :biggrin:

 

Hint: One drop of Orange nail polish did the job for me xD

The downside of that mod is it's not easily reversible, or if you wanna change the colors. You could drop some acetone to dissolve the nail polish, but then you're introducing more substance to the electronic circuit board. My solution is to color the tube instead.

When I first used red nail polish it was looking pink:blink:  But I just used a cotton bud with a bit of acetone to clean the topper led. And then it was white again xD

 

Just make sure you don't overdo it with acetone... You definitely don't want the polish or the acetone touch the circuit board, like you said.
