Hey Alonzo,
I was just looking at my stereomour top plate on one side of my bench and the exo-145s on the other side (figuratively, of course) and I had to wonder if thosetransformers would fit the stereomour chassis as it is -- well, bingo!, perfect fit and plenty of room inside. So now if there will be no issues with adding a 5k opt to the stereomour with 45s, that's what I'm going to do. my guess is that there will be no problem, maybe just a small adjustment in the cathode resistor and maybe the power supply resistor. I had planned on using this amp in our quasi home theater setup, but have decided to go with the SS ACA amps or s.e.x., and the stereomour in my main system. This is going to simplify things a whole lot, at least to begin with.
Nice going and let us know how those opts sound with some break in.
