i just ordered a quartet of electro-harmonix "hard" 6l6 tubes. i have no idea what the difference between hard and soft is. but i assumed hard ones would push the pre amp tubes harder so that i would get better distortion. i have a bugera 6262 and the power tubes need replacing. the amp is not as loud as it used to be, and isnt as driven. any help is appreciated. thanks.
They work better and last longer.
It will take more to distort them. Soft are the easiest to get to a clipping stage.
