I just picked up one of these, & although I "LOVE" the tone, it seems a bit underpowered. I know it's only 80 watts, & I'm used to using Twins, (Rivera II, & Red knobs). The 65 is fitted with Fender/Groove tubes,6L6 (Blue).They look like Sovteks. And GT pre amp tubes. Does anyone else have a similar opinion? I ask, because I keep hearing people say, they cant run these 65 re issues past 3 or 4 on the volume, but this is not what I find?
