I will go out on a limb, and say this - having built every Trinity kit that is offered...
If you take care, with your work, and follow the excellent manual and layout - and if you have anything that is not clear, ask before you take a guess... you CAN build any of the kits.
Assuming you can solder of course.
You basically follow the instriuctions, and layout. I hate to admit, but it is a lot like "build by numbers"

Thats OK though, it lets guys like me who dont have a lot of electronics knowledge build some kick ass amps!
