Hi all, I am needing to replace the speakers in my Twin Reverb SF. I am looking at the Celestion G12V70 (which I believe are in the current reissues). Despite all the comments and videos i've watched I still can't get my head around the Wattage and Ohm information. My TR has 100w output and 4ohms wired in Parallel & the 2x Celestions are 70w 8ohms each. Will these work fine with the TR?
