Hello everyone. I am looking to buy a re-tube kit from Euro-Tubes. I was just wondering if anyone had any downsides to the re-tube kit from euro-tubes. I am looking at the standard re-tube kit with the JJ 6L6GC's & the JJ ECC83S's. I am also going to pick up a pair of the GZ34's and try them out and see if i like them? Does this seem like a decent choice? Thanks in advance!
