Hi! Ive read a few threads about changing the tubes on the Art Tubeopto 8. I got my hands on some vintage telefunken ecc83 smooth plates and I can’t wait to hear how these sound! Several of the threads I’ve found note that you need to remove the tube snubbers before you pull out the tubes and replace them after. I’ve only ever changed tubes on amps where there are no snubbers involved. They seem pretty glued in. I was wondering if any of you have experience with this, and if so how you got the things out?
