Okay, it's Sunday evening here so i'll be nice. It rings. The two sides don't ring the same And i think most people find it worse on the right channel. This i stipulated that it is to do with where the tubes are located on the board - one is notably closer to the headphone jack and the vol. pot than the other. However this has not been confirmed as the actual reason.
And i assume it's not necessary to tap the case?
On my unit it rings opposite. Left is ringing louder and longer. If I want to hear right, I must knock vali hard enough. I did it only once as I do not want to make it worse because ringing is no issue for me.
When my Vali arrived I unscrewed cover. Both tubes were pressed to foam firmly, but I noticed difference. One tube is parallel to PCB, while other tube is pressed more at legs part - I do not remember what tube - left or right, difference is maybe 5 degrees.
thanks. I just hit vali once, to see how it react and how much does it take that ringing disappear, specially in the right. I hesitate to open my Vali. so I want to ask first and act then.
maybe I need to look inside the Vali. I can see that one of tubes, is in its place, but I can not see the other
