Active Horns require X3 sets of mono Blocks (Which tube match?)

[abbeystump]

My Line magnetic Tube Horn project will require 3X sets of mono blocks.I have a LM G-212 to run the 2X 15inch woofers.The horn and tweeter require smaller Amps.Question is should I try to match the tubes type for the sound for the tweeter and horn.I have been recommended the 300 tubes from a Line Magnetic 91A 300B.I will use a DEQX HDP5 to do the crossovers and room calibration.Can anyone direct me to website where this has been discussed?? As I need to buy components as funds become available the end result is the aim and may take 1-2 years to complete!!
