Hi Folks, I'm going to build a RH84 SEP amp after Christmas. I have all the parts except for output transformers. I think I'm going to start off with some Edcors. Firstly, is there any different other than the bell between the XSE & the GSXE series? My main dilemma is figuring out if I should go with 16ohm taps, or 8. My main system is an Altec two-way, 16ohm, however, most of my speaker collection is 8ohm. Is it smart to just build with an 8ohm tap due to future versatility? Happy holidays!
