Hey guys, this is my first post and I would appreciate any help with my issue. Ipurchased the PS1 attenuator a few months ago so I could get that "sweet spot" tone at lower volumes. 22 watts is surprisingly loud! It worked like a charm and my amp sounded phenomenal for about 2 weeks. One evening, the volume started cutting out and the tone got very fuzzy. I noticed the replacement light was on for one of the power tubes. Now I know what a dying power tube sounds like (it was actually a pretty spot-on brown sound!) I stopped playing, disconnected the PS1, and called Bugera the next day to see if there were reports of problems with the PS1 or it was just time to replace the tube. They said to just replace the tube and there were no known issues with the PS1 damaging amps when used properly. I went ahead and bought a full set of preamp and power tubes. I figured it was a good excuse to replace the stock tubes and see how that affects the tone. After replacing all of the tubes (which was pretty easy, by the way,) I plugged in and played without the PS1. Once I had a couple of hours of playing time on the new tubes, I hooked the PS1 back up. After about 10 minutes of playing, the power light started flashing and both power tube lights lit up. Again, I stopped playing and removed the PS1. My amp is less than a year old and works great without the PS1. I desperately want to use it but it's collecting dust now because I don't want to ruin my amp. This thing is rated for 100w and obviously my V22 is way under that. I made sure the PS1 was connected correctly from day one so I didn't screw anything up. I also take care of my equipment and only play at home. Any input would be greatly appreciated.
