DT25 clicks and pops when playing

[klasi]

I've got a consistent click/pop that comes from the amp's speaker when playing.   Not loud, but noticeable.  The popping resembles if you weren't playing and you touched your strings with your fingers and there's a little static-like pop.  However, it ONLY does this while playing.  Alot.  (And never on beat which is extra annoying.)

 

Also, I'm using the direct out and I get my sound in my in-ear monitor and in my ear there is no clicking or popping while I'm playing.

 

Ideas?

Solutions?

When was the last time the tubes were changed?

My clicks and pops when i'm not playing got it hooked up to helix via Line6 link but also when i just plug the guitar into the input jack on the amp
Just got it second hand so i dont know if the tubes ever was changed

Are you using Line 6 Link, 110-Ohm cable or regular 50-Ohm mic cable?

Impedance matters with this. It requires XLR type, 110-Ohm AES/EBU cable.

Yes i am using a DMX cable 

PD Connex DMX hmm the store i bought it on said 110 ohm i just googled and it says 120 ohm on some sites dont know if those 10 ohms really made a difference?

As it pops and clicks when i remove the cable and plug the guitar into the input jack aswell pretty sure its the tubes 

What is really strange is when i tested the amp in the store some weeks before they shiped it to me (i bought it on their webshop) it didnt pop and click so it might have been the shipping hmm

10 Ohms can make a difference, not certain if it would here. I wouldn't risk it.

 

When was the last time the tubes were changed out?

Are they the specified Electro-Harmonix EL84EH and 12AX7EH tubes?

Looking at its history, I wold say, play it safe and take it a Line 6 authorized service center

in your area and have the tubes changed out and the bias and burn-in procedure done on it.

 

Calibrations to be done done by an authorized technician who can dial it in and get you off

to a good start, as these require that the analog and digital sections need to talk nice to the

other to keep it all running well.

 

Tube change out should be done regularly,...

Every 12 to 18 months for serious performance and touring musicians.

Every 18 to 22 months for weekend performers.

Every 22 to 24 months for bedroom or home studio rock stars who play a couple of hours every couple of weeks.

 

 

Rock On!!!

I just found out the sparkling noise and popping sounds only happens on Class A/B on Class A it is quite and way louder in volume the Class A/B seems to be stuck on a very low volume nothing happens when i turn the master volume above half the way.
Well just when i write this it started to sparkle on Class A aswell for a short moment.

"The sparkling noise sounds like a guitar with a bad soldering and the noise is similar the sound when you turn a tone or volume knob and the pop noise is similar to the pop sound yoy get when you switch pickup on a bad soldered switch but it is way louder on the DT"

I bought this DT25 head in a music store and it was a used amp the store is located 550 miles from my home and when i tested it in the store before i bought it it sounded perfectly fine and was very loud in volume now it is edroom volume even if i turn off the low volume mode (i usually use  low volume mode as i live in an apartment) so my guess is that something has happen during the shipping
It wasnt packed so good only some bubble plastic those big ones with lots of air in them and also some papers around the amp and it came in a paper box it had no no styrofoam which is almost always common on new amps well i say all new electronic gear you buy.

Have you heard of this issue before?

I really like this amp but this issue is worst than all my Marshall heads i use to have in the 70,s and 80,s on those i could sometimes hear Russian or Polish radio stations (or was it military communications) but it was way more quite than this.

Dont know if it is profitable to send it to a repair shop as that would cost about the same to what i would pay for a used one that is in good condition.
