If this question has already been asked, I apologize. Recently I had the power and output transformers replaced on my 1963 Ampeg B18 with original canned ones from Fliptops. The Cleveland 18” speaker also got reconed to 8 ohms, which is what it was originally. Now that it’s all back together, I’ve noticed a slight drop in overall volume from the amp. I’ve tried the amp through another cabinet, Eminence Delta lite 15” 8ohm, and the volume is what it was pre recone. Do the replacement transformers work better on 4ohm speakers, or did I get a bad recone? Or is there something more to all this? Any help would be greatly appreciated.
