Happens over and over. #1 thing that goes wrong in the shack ... cables, adapters and connectors, busted, wrong, wrong wiring, don't fit, etc. And it's often the LAST place we look.
Speaker cables/connectors need to be very low resistance. One point of issue is machine-crimped pins in a connector that grab insulated wires and penetrate the insulation. It's possible for the pin crimping to contact only a few strands of the stranded wire and pass automated continuity checking but be entirely unsatisfactory for the low R speaker use. Also a bit of patina on a pin or mating surface can do the same thing. Glad you found it before you sent 'em back. That's sooooo embarrassing. I tore apart an amp once, in the middle of a multi-multi contest effort, where the problem turned out to be the RCA plug on the cable for the amp's relay connection. That was sooooo embarrassing. 73 and happy holidays, Guy K2AV On Thursday, December 24, 2015, Mike VE3YF <m...@ve3yf.com> wrote: > I received my pair of SP3's last week and I also had a problem, where I > could get stereo but 1 spkr would always be weaker in audio than the other. > I contacted Elecraft and they couldn't figure it out either.
