It finally came. What I got was an RM100 metal face edition. Feels great to be coming back to the MTS series. It came with two KT88s and two KT66s (which is like an upgraded 6L6). Biased her started her up but I have no module until Friday! I can say this much. With the KT88s and KT66s this amp is going to sound HUGE. I threw the 88s on the outside of the two and the 66s in the middle. The outside controls a lot more of the headroom and bottom end while the middle tubes control the mids of the amp. I hear 66s are great for their mid range. Family shot anyone?
