Whenever I use my F1-X (always in conjuction w/ my SF-2 superfilter and my Markbass- amp) I get these annoying & damaging electric, loud "pops" that overloads my amp. these sounds are independent of bass-choice(elan & epic), cables and grounding, &c. could the choice of voltage cause this problem? on the F1-X you can choose between 220V and 240V. we have 230V in sweden...what would you choose? best regards from sweden/ kristjan aunver

hi, davehouck, and thanx for your promt reply. I talked to my tech-wiz and we agreed that these "pops" might orign from a defect 12AX7-tube. because this annoying effect doesnt come until the amp is warmed up. Im gonna try this theory with a spare. changing voltage was no remedy. Im stuck on 240V. thanx from sweden/ k aunver

I checked with dad, and he says he would use the 240V for Sweden.

Let me know what you find after you change the tube.
