I'm looking for recomendations on great sounding output transformers for the 6C33C tube. 600 ohm Primary imp: 8 ohm secondary imp: that will be clean and open full range with a 30 watt rating.
Use will be in SET monos rated at 15 watts. I am looking for square units, encapsulated for top of chassis mounting (they look similar to a Cary chassis)
Even the mighty Google comes up short on options.

I am using some custom James trannies right now and I think they may the weak link right now (sound a little closed in)
Any help from the circle's 6C33C tube lovers would be appriciated (brand & source)
