Hello Everybody, I'm happy owner of Zen Torii mk III for the last 2 years. Unfortunately form some time I can here cracking in my right channel when I'm trying to volume up. It is not really annoying, but... so Please help me?
Oh and second question: what are you guys using to clean your tubes sockets? Thx Peter

If it is only while you are turning the volume knob it could well be the contact in the volume control is dirty. If you find this to be the issue, might best call Steve since this would be a warranty thing whether you send it in or fix it yourself. I have successfully cleaned the internal volume contacts with Deoxit cleaning fluid or spray, but you have to know what you are getting into...drain the stored cap energy from the amp. Otherwise...could be very, very dangerous! I use Deoxit for my tube sockets too.
