the rt2/50 has 6l6's and el34's so is there a tube for the yj's that i can kinda keep the idea of this? a pair of tubes that will give me a 6l6 sound and a pair that will give me a el34 sound? id hate to mod this amp and loose that feature, but i like the idea of cranking it and pushing the tubes at lower volumes. im going with the yellow jacket triode to reduce the power up to 70-90%.
