You can do anything really. Parallel triode can be setup to add gain but I would question this at v1 as you Will Never have a clean tone.
Tubeswell and Sluckeys advise la sensible and just. as me have been playing geeetar a while that said we will lean towards the complexity parallel stage provides. No dual triode is perfect. There are some imbalance. This adds thickness, but it is a balancing act. To much and you can never get a good clean.
NOW, one thing I disagree about is the Train wreck. Trainwerck does distort in the preamp very early and driver the output tubes with this. I have built a few. You can most certainly build a wreck in a blues Jr, but the power trans is short on ht amperage. And they usually sound better with 6v6 when using 2 tubes. El84 overdriven too easily when using only 2 of them. Headroom is a problem.
Read up on cold clippers and consider using either one in the unused triode stage or consider a small pentode like is discussed at great length in the book Sluckey suggested. If you have not ordered it yet You are not serious.
A train wreck is one of a kind and NOT for inexperienced builers, but if you want to builds one I have a detailed guide. No, I will not do a layout or schematic, I wouldn't want to cheat your learning. Sluckey rode my butt until I finally began doing my own.
This is so HUGE to understanding and successfully building a stable amp. I know, we all want it now. I am still learning a lot all the time and built many amps that had to be disassembled simply because I was in a hurry and considered the advice from the extremely knowledgeable to be over the top and really not necessary.
Here is the deal. You have to decide if you want to learn, or just want an amp. If you do want to learn get the book and even Morgan Jones valve amp book. It is a little more hifi oriented, but you will learn screen dissipation and many other tips on how to build very quiet amps.
If you just want an amp,, simply state what you would like and ask if someone wants to build it and for how much. You can build an amp with only a multimeter, but you will never really understand until you see the signal. Oscilloscope get it, connectors probes. 2 channel and doesn't have to be a Tektronix. There is nothing in a tube amp that perfect.
After all this, if you already know all of what I wrote, please ignore it all. I am just telling you my mistakes and in no way ragging on you.
