I have encountered a problem this evening that has me scratching my head....maybe someone smarter than I am can offer a suggestion?
I received a new pair of interconnects this evening and plugged them in between my Tortuga preamp and my Job 225 amp (I recently put the same interconnects between my Schiit Yggdrasil DAC and my Tortuga preamp) I turned on the preamp at very low volume and then turned on the Job. I immediately heard a screeching sound from my left Cain & Cain Abby speaker, so I turned everything off after just about 2 seconds. Next, I made sure everything was plugged in properly and tightly (preamp, amp, speakers) then turned the preamp and amp on again. No screeching sound this time, everything works fine except my left Abby speaker now produces no sound - but what's weird is the Fostex supertweeter wired to the binding posts of that speaker puts out sound just fine.
I have switched the new interconnects to the each other's imputs on the amp, I put the old interconnects back in, I attached the right speaker cable to the left speaker, always the same result. The tweeter works fine, no sound from the speaker itself.
Because the Job amp has the speaker outs directly above (and close to) the interconnect input, it's possible I accidently plugged the interconnect into the speaker out when I reached behind the amp, but I don't think I did.
The fact that the left tweeter is working makes me think the amps are fine and the speaker is getting a signal, could I have shorted something inside the main speaker?
Any thoughts you have would be greatly appreciated!
