hi all, the other day when i turned on my rockmaster i noticed a substantial loss in volume, probably greater than 50%.

along with it , the tone is flubby and there is some breakup in tone, its particularly noticiable on the clean channel, if i hit the strings hard i get a harsh volume burst representing the volume it should be at

I changed all the tubes today and its the same,
The power amp, guitar, cables are all ok too,

Anyone have any idea what the problem could be

thanks
