Hi, I apologize in advance if this is a dumb question, but is the tube in the Le Preamp replaceable? If it is, is it something easy I could do myself, or does it require sending it to a certified tech to open it up so that the warranty is not voided? I was just about to order a Le Lead when it occurred to me that how to replace the tube isn't mentioned at all in the manual, and from the pictures and descriptions online it's not clear if the user can replace the tube or not. I assume that it is replaceable, but just wanted to double check before ordering one
Thanks!
Thanks!
