Yeah, this had the best success. Tried electrical tape, which was not as effective as using duct tape. Which has 1001 uses, now 1002.

Just reporting in! Receiver still sounds great, getting daily use. New Polk speakers are good also, a small upgrade from what I can tell. Even though they were packed and shipped just as poorly as the Carver (separate seller, what are the odds?!) I had to massage the silk tweeters into shape, as they were dented and crushed. Got most of it (see picture. Open to suggestions having tried finger pinching, duct tape tugging and even a vacuum cleaner). Dude removed the protective grills before shipping (!), you know the shields that guard the domes and cones of the actual speaker, and shipped them like so. Told him not to do that for future customers. He compensated me 35% so I'd say ceterus parabus as it all worked out. Pictures you ask? Love to! Let's make a game out of it, who can tell me which song is spinning on the Oppo? I'll be lurking for a while on the forum so reach out! Thanks for all the support and a real shout out to kve777 who gave excellent advice.

Was thinking of upgrading anyhow 😜

Hey folks, just wanted to report that I got the MXR130 up and running! Turns out I didn't blow a component on the unit after all, I simply blew my speakers. Replacements are on the way... But I had some Bose 201s lying around, so I plugged them in and I'm off to the races! I am enjoying the sweet sound of the Carver unit. Nice sound stage, cleaner than the Pioneer 3700 I've been using since the 80s. Thanks for all the support!

Generous and helpful group! I will PM you, thanks.

Yes, to both questions! Jumpers are in place and I tested it with the turntable first, and it sounded good. I am thinking the solder joint theory is holding up. If I'm lucky I will be able to eye ball it for myself.

Hey folks! I do have an issue and I want to gather some collective wisdom from y'all, but first I want to say "Hi!" because I just discovered this forum. I'm a proud owner of a Carver unit, something I've been hankering after for many years and this one needs a little TLC and more importantly a bit of troubleshooting. I picked up a second hand MXR 130. Thing is built like a tank. I know this because it was shipped to me in the second worst packaging and careless handling I've ever witnessed and it still fired up. Tested audio with some records and Bluetooth tube preamp that I attached to the auxiliary port; sounded great. Shuffling some of the stereo components back to the original position, the cable connected to AUX got loose. It was very noisy and angry... I pushed it back in and got some loud buzzes and oddly to me a high-pitched squeal that triggered the relay. But no static per se. Now when I play through the Bluetooth preamp, it is mighty silent but >0 dB. All in the high frequencies, audible at higher volumes but heavily filtered. Thinking it was the port, I switched to another input but the problem remains. Even the phonograph, which was never even connected to the unit that was connected to the crackle port we'll call it fails in the same way. If I jiggle the connector, I sometimes get that high pitch squeal which lasts for a fraction of a second. Like a chirp. Help! I really dig the unit, and although I knew it needed some TLC (LED display doesn't work and I'll need to get a crossover circuit for my subwoofer, but that's design related) I really didn't think the audio would be this compromised. I'm assuming it's age of course. I'm hoping I didn't blow the amp, but like I said I'm hearing music, just reduced to about 10% gain. It's not in any protected mode, the relay does its job. I can hear it click on power up and it even triggers when the volume is too high, like 8 out of 10, even though it isn't that loud. I ordered some Deoxit, I plan to spray it liberally. But I'm open to any suggestions. Including repair centers in Massachusetts, or reputable ones that I could ship this to. Thanks for reading this long post, if you come this far you owe it yourself to help out LOL 😆
