Hey
So i have had this amp since 2016 and i play it a lot. mostly at home on the 5 watt mode. Today as i turned on my rig and put the amp on from stanby(around 20 min) i start playing and the volume starts fluctuating from loud to soft and back on its own. I investigted some patch cables in my pedal board to see if one was faulty and finally just went direct guitar to amp. The fluctuations kept happening. eventually i turned it off and now am writing this!
Now where i live the mains are at 220 and this amp is a US voltage amp so 110. I run it through a power transformer and its worked fine for the last 4 odd years. Never ever had this problem.
Do you guys think a tube is busted? or something else is the culprit. Guitar pots are fine no problem there. the cable and input are all fine. It has to be the amp. Do i need to change out the tubes, have these ones worn out or do you think its my electricity thats irregular?
I connect the head into 2 different 'cabinets' basically 2 combo amps have that im connecting to the speakers of directly. both are at 8 ohm. again, ive run this setup and play almost everyday and this volume thing has never happened.
Any help is much appreciated!
Hello Shashvat,
We would recommend that you have the amplifier looked at by a qualified engineer so they can check the valves for you to see if this is causing the fluctuating volumne.
