Tried swapping tubes (R to L, L to R), the crackling sound still remains on the same channel (right). It doesn't get louder when I crank the volume. Tried leaving it on for a while before trying the amp again. Tried cleaning tubes. Not sure about cleaning the sockets, which are the main suspects to me, since I was afraid of f'ing things up.

if you swapped tubes, cracking sound ... might be bad capacitor.

try swapping input rca cables, maybe canned air in the sockets too, and of course, reboot the amp

@bilboda Tried not plugging in any RCA cable, still crackling noise. Haven't tried canned air yet, will do, thank you!

@purr1n Aw. Is there anything I can do with the bad capacitor without sending the amp across the pond?

I'm sure there's a local electronic repair shop around you that should be able to fix it up.

@famish99 Good to know it's nothing too complex to fix!

Thank you all!

Be sure you ask @Zampotech before taking it in for a fix

Swap the tubes. Put the left tube in place of the right one and Vice versa. If the crackle changed the channel, the air gets into the tube. If the crackle did not change the channel-see the contacts of the tube socket. It is possible that some contacts are unclenched and do not have a stable electrical contact.

@Zampotech Swapped the tubes, the crackle remains on the same channel. Should I just bring the amp to the local repair shop?

Can you give large photos of the tube socket? I want to understand what is the source of the crackling.

Another point. Are there any sounds in the headphones when the amplifier is turned off?

@Zampotech Oops, I've just sent the amp to the repair shop. :'( He did a quick check and there seemed to not be any trouble with the socket. He still needs a few days to thoroughly check everything since his repair queue is long.

There's no crackling sound or anything of the sort when the amp is off.
