I believe I have an issue with one of the PS2 units I own. Ive been using it with a 100w Super Lead for the past couple years and haven’t had any issues with this particular unit (I own 2) till now.
As I was recording in silent mode the signal started dipping a lot, then suddenly went very loud. This was followed by a Valve blowing in the Super Lead along with the HT fuse being taken out pretty violently. I got the Super Lead sorted and it returned today, assuming the changes in volume were just down to it being about to give out. I’m aware valves have a finite life span so it seemed normal, although rather annoying.
I plugged things back in and something immediately wasn’t right. It was much louder than it should be, sounding as if the actual signal going into the load section was clipping. There were a few weird dips as well just like it was before the amp blew previously. This is all in silent mode.
Long story short, after a process of elimination, I tried running the exact same signal route with the same cables through my other PS-2 unit and everything was fine. I went back to the unit in question and the signal was not. I’ve recorded a sample of each so you can hear the normal sounding one and the other. It clips at the start followed by a big drop at the end. Please see follow this link to both the examples on Soundcloud: Stream George Twydell | Listen to amp playlist online for free on SoundCloud
Do you guys have any idea what this would be? Please also note I always have the unit on for the fan when using it with the 100w.
Just want to check a few things. I’m make sure the FX loops is unplugged and the level switches in the front panel are the same as well as the reactive load toggle switches.
If this is the case, then I think you have eliminated and differences. So just changing power stations is the only difference?
Yes I tried without the FX loop, running through my 4x12 and had the same strange clipping and volume blips. All switches and settings the same when comparing on both units. The unit itself made the difference.
Also worth mentioning using it as a power amp works fine still. I have a UA FX Lion pedal that I can use through it. It’s just using the real amp which is causing the issue.
I could listen to the clips. Yes I can hear the volume drop out.
Do you have a multimeter that can measure resistance? If not, I’d suggest sending it back for a service. The only thing I can think of is that there is an issue with the reactive load. If you do have a multimeter, with the power station off, disconnect everything. Then plug in a speaker cable to the Amp In and measure the DC resistance between the tip and shell at the other end of the cable.
I tested with a multimeter and it wasn’t giving me any reading back. Seems like the load section is indeed buggered
I bought the unit from Guitar Guitar a couple of years ago and their website says they have a 3 year warranty so I’ll contact them tomorrow.
If for whatever reason they can’t do anything it would be much appreciated knowing the closest recommend Fryette servicer to me, around Reading, Berkshire.
Hey dude I managed to get it in contact with Guitar Guitar and it was indeed still under warranty with the them.
I’m gonna see if they will sort the other problem out too but after this problem is sorted. Still need at least one with me so I can use the power section for in the meantime…
