Can I assume by that, the rec. Tube is going to have a less "dramatic" impact on the sound of any particular music piece than the signal tubes will?
relationship between rec. and the other tubes?
New to tubes, in my pre I have (1) 5z4p rec tube and (2) 12at7 tubes. What is the relationship between them? When I change diff. Brand 12at7's it affects the low and high and mids. Not sure what the rec. Tube does? Tyring to get a handle on this. Any help is appreated! Thanks.
