Help Please on my Amp build
Can any of you audiophiles help me with this question ? can a Tube Preamp enhance an A/B Amp . I've read conflicting info on this subject on the web with authors saying high end boutique amps use this set up. But after watching a Bob Carver video he explains how a tube Amp works with it accepting return power to the tube by reflection of the driver and an A/B cancels this effect. So I'm confused now thinking maybe a tube preamp would be a waist of money.:(http://https://www.youtube.com/watch?v=LQ9USqpclWc
The amp boards are 4- Yuan-Jing 3 x TDA7293 Parallel 250W Mono Power Amp Board .
Any help would be greatly appreciated....
Tubes have a sound quality to them that some like but they also have higher distortion and less linear frequency response. To the ear they might be pleasing, for some, but overall I think they degrade the clarity and neutrality of modern amplifiers.

why is the bridge rect. so far across the chassis from the transformer?
if you want to experiment with a tube pre-amp there's all sort of tube line stage kits and no offense intended at higher voltages bad construction technique becomes lethal fast!
and the ocd part of me wants to lead dress that medusa of wire into twisted pairs (unless as is, it's not noisy)
