Mine are "lightly gripped" in the WA5-LE, which is odd considering the death grip the amp has on every other tube. Having said that, once I re-seated them the ringing went away.
I think it definitely will. Keep us posted when you have time of course.
An update on my ringing issue. I have finally had some time to do some tube swapping and I think it is definitely my Elrog 5U4G. Swapping out the Elrog for the stock rectifier the WA22 came with, (sadly, all I have right now) it becomes clear who the culprit is. The ringing is shockingly audible in the room. I have tried re-seating the tube many times, and also using a socket saver to try and see if that could help matters. The problem remains.
Does anyone have any thoughts as to what might be causing this? Perhaps a faulty tube? It's unfortunate because the Elrog is a rather fantastic rectifier (and the stock one is...not great).
