1 Mikey 5 months ago Hi all,Long time since I've posted, but I'm looking for some advice. I have a stock Excelsior which has been sitting unused for quite a few months. I actually listed it on craigslist and of course when someone showed up to try it I fired it up and heard this TICKING sound. I can't find anything specifically related to the Excelsior with this issue so far in my Google search. The ticking starts once the amp warms up. It is very pronounced when the guitar is plugged in and my hands are off the guitar. It is much quieter when playing but still there. I read something about this likely being one of the 12AX7 tubes, and related to the tremolo. It makes some sense given the rhythmic ticking, but it doesn't change it's speed or volume when the tremolo is on, nor does it go away when the tremolo is off. I will likely just start by trying new 12AX7's, but curious to know if anyone else has experienced and resolved this same issue. Thanks for any help!p.s. I posted this exact thread on the TDPRI to see if anyone there has seen this.
