Fellow AK's, We'll I bought and hooked up a used Realistic APM-200. I checked all connections, except I set the impedance incorrectly. Duh. I set it to 4ohms, not 8ohms. I turned it on and didn't see a lot of movement on the meters, so I turned it up. The amp clicked off. I freaked out and realized my mistake. I changed the impedance to 8ohms (to match my Cerwin Vega VS-120's), and it all came back on. BUT....now neither tweeter is now working. Mids and woofers are OK, but nothing on the tweeters. Is it possible to have blown BOTH tweeters with my ignorance? Is it possible I blew up a capacitor? I don't think I hurt the amp, right? It's still cranking away, but only on the mids and woofers. Ugh....any help is appreciated.
