Nah it already has the same 6V6s

I just got them as spares.
I wouldn't know the difference man... I barely ever use the amp, I still have the older valves but they were as old as the amp, close to 18 years old. Only been changed once, but put back in later. They were of the smaller size. I didn't compare the tone nor cared/wanted to. I just learnt how to bias, popped the new ones in, biased, didn't kill msyelf and that was it
