I've not tried an Edcor power, I have the outputs. Most of them are made for tube rectifiers I believe. I'm not fond of tube rectifiers in amps above 30 watt, ,certainly not 100 watts. Were you planning a tube rectifier? Which one?
What output transformer might you buy?

Thanks for the response Roger. When you say "made for tube rectifiers" are you referring to the center tap? If so, I'm under the impression that I don't have to use the center tap. I'm not an expert but based on what I've read, I'm not a fan of rectifier tubes. I currently have 2 sets of tube monoblocks and neither of them use tube rectifiers. One uses a quad of EL34s and the other uses 8 KT88s per monoblock.
As far as output transformers go, I don't have a specific one in mind right now but I would consider an Edcor or Lundahl. I would only use the latter if I were very confident with what I was building because of the cost. I would love to know how much difference really exist between the two.
I was considering building a lower power tube amp (25 - 50 watts) if I could find speakers that I could afford that sound good with a medium power tube amp. The problem is that I keep gravitating towards less efficient speakers. I used to have Thiel 3.6s and I still have a pair of 3.0s in storage. I had to move to a smaller room (11' x 16' x 10') a few years ago and I've spent the last 4 years learning room acoustics. I'm using a pair of LS50s right now, which sound really nice with both sets of monoblocks. BTW Roger, I still can't believe how much of a difference it made when I moved the LS50s from the 8-ohm tap to the 4-ohm tap on both sets of my monoblocks.
