[QUOTE="Rilke, post: 155465, member: 3746"] Hi all! I've recently ordered some new powertubes for my rm100 head (2 Genalex Gold lion kt88's and 2 EL34b-STR TAD's) to replace some older sovtek el34g's that are presently in the amp. Besides that I'll be changing v1 & v3 preamp tubes (first preamp tube + phase inverter, tbh I don't know which tubes are presently in those) to two NOS Raytheon long black plate 12ax7's. The plan is that I'll record some tones before ANY changes/after preamp tube changes/ and after preamp+poweramp tube changes, so I'll (and by extension you guys) can be able to hear how each of these tube changes affect the overall sound. My plan is to record the changes through my Salvation Mods Mamba as it is the module I have I presently like the most (have the S1S0 + Angel-E aswell). The RM100 in question has the Salvation mods MDA upgrade installed aswell. Let me know if there are any requests or questions or pitfalls ( Definitely regarding the pitfalls :) ). If I have the time to rebias twice, I'll audition the poweramp tubes with both the KT88's in the two center slots and in the outer slots, so we can see how that affects tone.
