jackTaylor Posted September 12, 2023 Share Posted September 12, 2023 I inherited my Dad's Heresy Speaker set, don't know if they are 1's or 2's. After opening up the back of it, seems to be circa 80's based on the size of the caps and the font (lol). I love these speakers and it doesn't seem too hard to fix? I just don't want to break them more. Can anyone point me in a good direction of replacement parts or maybe trouble shooting whats wrong? I'm definitely lost.. Problem: One of them stopped working, no sound Initial trouble shooting: Checked connections to amp, ran the speaker wire through hand to make sure it wasn't pierced/crimped. checked the connection to the cabinet. tightened all the screws on the board. No sound. took my multimeter and checked continuity on woofer, mid, and tweeter. got a beep and all three. Assumption is its the capacitors or what looks like two little transformers? Question: Where can I buy new parts, not totally sure what new parts I need. Thank you! 3 Quote Link to comment Share on other sites More sharing options...
billybob Posted September 12, 2023 Share Posted September 12, 2023 Welcome @jackTaylor...have you tried switching the speaker wire from the amp to try and eliminate the wire and the speaker? Right to Left input on the amp. Let us know... thanks! 2 Quote Link to comment Share on other sites More sharing options...
Dave1291 Posted September 12, 2023 Share Posted September 12, 2023 As @billybob pointed out it could be one side of your amp/receiver/source is toast. I have a pair of 81's here and zero problems. Prolly be something simple or could be more complex. Speaker balance knob centered on the receiver? Kinda tough w/o knowing what your running. Check the dead side wire on the other speaker if it's not the balance? Something's goin on. 2 Quote Link to comment Share on other sites More sharing options...

Satisfactory capacitors can be had from several sources. 1 Quote Link to comment Share on other sites More sharing options...

Dave1291 Posted September 13, 2023 Share Posted September 13, 2023 This isn't rocket science yet. He's assuming it could be the networks but that's really the last thing on the hit list imo. It's possible, but let's work thru it as far as we can go before we jump into where to buy whatever he may need. Hence the topic really isn't closed until he figures out what HE wants to do. There are ALWAYS opeions and that's his call. Sure I could have replaced mine in my 81's but they sound fine right now and aren't my primary rig. Sure they could sound better w/a new kit but... Could replace all the speakers too while we're at it. 1 Quote Link to comment Share on other sites More sharing options...

grasshopper Posted September 13, 2023 Share Posted September 13, 2023 I'm a mechanic, not an audio tech, but... there are a lot more things to go bad in an amp. 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted September 13, 2023 Share Posted September 13, 2023 Yes so, after the OP was done with the simple test, we could know what to do next with the troubleshooting. The process of elimination would eliminate the complete system, pointing to the culprit. One should not jump to conclusions until...focus is the way. OP may well be listening to music now in stereo, or not. 2 Quote Link to comment Share on other sites More sharing options...
Dave1291 Posted September 13, 2023 Share Posted September 13, 2023 My buddy has some big Sansui receiver and told me it was blown. He wasn't getting anything to his speakers. Seems as though he had a habit of cranking it with the "loudness" button pushed in when he was trashed. Had to have that boost. lol He wanted me to run him down and have a friend put it on his bench so I told him to get it here and we'd make a run someday just so I could BS w/the dude. Been a few years so he shows up with it. I let it set on the table. lol About a week later I figured it was time so hooked up a pair of speakers and yup nuttin honey. So I look up the amp and nosed. Found out the loudness button had a safety reset on it. lol I pushed the button and turned it off . Fired it up and it worked fine. lol Told him I fixed it for him and he thought I'd taken it into the shop w/o him. I said yup, you owe me $75 for the bench charge so he paid me. Should have kept the money to replenish the beer he drinks here but I didn't. Guess I had a weak moment. 😂 1 1 Quote Link to comment Share on other sites More sharing options...

Satisfactory capacitors can be had from several sources. Satisfactory capacitors have always been available from many sources, that’s true. However, the only source for replacement capacitors that have been tested by Klipsch Engineering to insure they meet factory spec, not alter the transfer function, and perform as intended, are from JEM performance if you want the parts and can solder them in yourself or @Deang if you would like him to rebuild your networks with factory approved and tested parts. 2 Quote Link to comment Share on other sites More sharing options...

Let’s go step by step, figure out if it’s an amp/preamp problem which @billybob is checking on with left to right wire switch. If it’s the AMP/Receiver then we can see what the labels/SN say and we can tell him how old and whether they are good to go or if he may want to consider having them rebuilt.

jackTaylor Posted September 13, 2023 Author Share Posted September 13, 2023 Wow you guys are amazing, it was a newer amp so I never would have guessed. Channel was fried. Can’t thank you guys enough would have been the last thing I would have checked. 3 1 Quote Link to comment Share on other sites More sharing options...
