I stumbled upon an ebay Auction for an Eminence Swamp Thang with 1 minute left and a great price. I bid as quickly as I could only to read the fine print (after winning, of course ...DOH!) to see that it was a 16ohm instead of the 8ohms that a DR calls for. My DR is a ptp reproduction of the ab763 circuit using a repro chassis but current production aftermarket trannies. The guy who built it for me says that there wouldn't really be any problems using a 16ohm speaker (and I trust him implicitly) but I'd like to get anyone else's thoughts on the outcome. 1. Would it cause extra wear on tubes or trannies? 2. Will it adversely affect the sound? thanks in advance.
