It only makes sense if you're designing new and untypical circuits. And the loadline won't tell you how the stage sounds. I don't see where you could use/need load line construction here. If anyone has any thoughts on a mod for this, or any advice on doing the load lines I would appreciate it. Similarly the load impedance gets pretty tricky when you have relays and switches and tone stacks. You can't include those because there are other tubes drawing current from different nodes and dropping the voltage, yet it doesn't seem like you can ignore them either. Most tutorials seem to assume that there is a tube with a plate resistor that is connected directly to an ideal 200V (or whatever) voltage supply, but my circuit has a plate resistor and then there are a bunch of other resistors that drop the voltage down from 450V. I have looked at tutorials and what not for drawing load lines and they all sound really easy, then you get to the actual circuit and nothing makes sense. I was thinking about trying to mod the amp a little to try to get a modest boost in gain on the input (or close to the input). I have seen others make similar comments about this amp. I have had a basically identical amp in the past and one of the things that I didn't like about it was the inability to get a full sound with single coil pickups. I'm in the process of fixing a late 80's Carvin X100b (gray rat fur covering, block letters).
