Different categories of tubes light up differently as for noise maybe if your tubes are new first thing clean the pins so you have a better contact personnally i use light sandpaper to clean the pins and that should do it if not maybe burnin if not maybe its a bad tube but first clean the pins that should do it

No luck theres also an audible hiss aswell(white noise) in the little dot. I'm sending it back for a replacement. Something's not quite right as it even struggles to amp my 32ohm headset even when switched to 600 ohm settings. Ive burnt it in for about 6hrs a day for the past 6 days and cleaned the tubes too. It's a nice looking amp just looking forward to getting the replacement.

if you  read your manual and your settings under the littledot are setup right for the  family of tubes  you are using ef95 and ef91 -92 familys you have to set jumpers accordingly you know that right her are pics just in case

I was a little hesitant buying it from ebay but the seller has been great with the warranty. Even though I have to pay return shipping fees I'm quite happy I'm getting a new replacement :)

Unfortunately it wasnt x2 days after I placed the order I released David was on ebay. However the guy I bought it off has been really good after he found out it was faulty. He has emailed me almost everyday just to check in and see if the problem has rectified itself with a burn in and he is happy to exchange it with either a refund or new unit. He has a 100percent positive rep on ebay and has sold about 3200 items with no negative feedback. I've sent the item back and when he recieves it i will get a new item in return. Thanks again Mikelap you give great advice and helpful info.

Is it normal for a loud popping noise to come out of headphones when turning on the MKIII?  Or when plugging the headphones in if the amp is already turned on?

Yes it is mine doesn't pop when I turn it on or off but it DOES when plugging my headphones in or out while it is on, and loudly too. So I just make sure I have the phones plugged in that I want to listen to before I turn it on. I also turn the volume all the way down too, then slowly turn it up once the music starts. I am pretty sure I read something about that in the manual as well.

Hmm...I'll try again. I was scared so much when it happened the first time, I heard a loud heavily distorted pop from the T1's, and thought its over...there goes 1000 euros down the drain. But luckily nothing happened to the headphones, at least I can't hear any difference.

Could anyone provide me with a piece of information please?  I need to know in which order the wires are soldered onto on the volume pot on the MKIII. A picture of a soldered volume pot would be a life saver.  :p
