Thank you Mikelap! Yes you are right. So I may going to buy a new rectifier tube while waiting to get a reply from Woo Audio for a possible replacement of the effected tube. What do you guys think about the Sopha Princess 274B? I appreciate the looks of it. Is it compatible with my new WA6-SE 2nd gen and what do you think about this offer? https://www.ebay.com/itm/Princess-S...684512?hash=item3d538bee60:g:VuEAAOSwIGJaOJRd Happy Holidays to you too!
