people worry about technicalities too much, these plates are easy to build and as long as you use some common sense they sound great. i used the Vidsonix Ghost, EMT pickups and sent the output of the pickups to some triad transformers and then into the console preamps to boost the plate output - drove the ghost with some cheap power amp and tensioned the unit to the wood beams in the A-Frame I was living in...which wasn't ideal but worked fine:
It took a day or so to complete.
Here's a sample track that used the reverb: Climb to the Top | Ryland Bouchard
or "All I Need" a track from Lana Rebel, from a record we did out on the front porch when I lived at the A-Frame...the plate was the only reverb on the track, other than the trees: http://www.lanarebel.com/listen/
Anything you do will sound better than if you do nothing at all...many studios back in the day couldn't afford EMT plates and did similar things...so be creative and make some music.
