feedback

Absolute Positive FeedBack for AK member rotobadger as a seller. Can't say enough good things about him. I had purchased a tube amp, he was great with communication, it arrived quickly, very well packed and safely. Everything was as described and rotobadger is one of the few who still cares...

Hi, I have posted a long thread recently about my quest to eliminate acoustic feedback between my new subwoofer and Empire 598: https://audiokarma.org/forums/index.php?threads/vibration-analysis-bl404-rack-empire-598-turntable.975735/#post-15167454 I am happy to announce that I finally found...

Just got a dial pointer from @Leestereo , it came well packaged and in great condition. Thank you very much for helping out the restorer community! Regards, -Otavio

Hi, I am a happy owner of Empire 598. Last week I also became happy owner of Rythmik F-12GSE sub. That thing is fantastic and has real infrasonic capability! Which, unfortunately, leads to feedback issues on lower volumes than I used to have with Paradigm sub (where I could cut low end with...

Been awhile since I’ve posted here but I’m trying to solve for a grounding issue in my setup. I have electrical hum/feedback at higher volumes whether I’m using my turntable or an aux cable to an iphone/CD/etc. My turntable (Denon DP-300F) does not have an external ground post and the grounds...

Hi y’all, first time long time.. I have been using a SX 636 for the past year, initially just with a tape deck and AUX cable (phone) while I was waiting to ship my record player (LP120-USB) to myself from storage in my home state. Once I got my turntable successfully shipped and began using...

I have an Onkyo Tx-2500 (mk1 version). Last summer it started making a bunch of loud crackling noises (like the sound you'd get if you dragged your fingernails across a live microphone) accompanied by a deep bass noise (sort of a pulsing womp womp womp womp... sound). This happens even when the...

I recently hired jlovda to recap and update my McIntosh C33 preamp, which is a complex beast with all kinds of boards and subsystems. John did a beautiful job both visually (clean work) and aurally — the preamp is now even more quiet, transparent, reliable in every way. John also worked...

Hi y'all, hope you are staying healthy at home! My main home activity has been to recap/rebuild a Kenwood KR-5600, and things are going pretty well for a difficult layout - except the inevitable mystery problem has cropped up. Maybe someone else has heard of this? It goes weird when the...

I'm rebuilding a Kenny 5600. Original description was "one side out", and all the lamps are out. This improved some with deoxing the controls, but there were two anomalies. The FM had terrible distortion on one side, and while checking a signal thru the AUX, the Treble control, when turned...

@hjames recently sold me a Vandersteen VCC-1. The transaction was easy, fast, fair, friendly. I got the center speaker in perfect condition (just as described) due to her careful packing. Looks and sounds great in my 5.1 system. Thank you, Heather! Nolan

Hi there, I was given a 70s Sharp RT-2500 cassette deck by my local library. It is beautiful and still works, however, whenever I press play, even without a cassette it creates a loud, high pitched feedback and the VU meters hit the ceiling. Can anyone help me out?

I bought an amp from him which was packed carefully and arrived in great shape. His description of the condition was accurate and clear, and communication and payment were easy. All in all an excellent transaction and I wouldn't hesitate to deal with him again. Many thanks to an excellent...

Here we have a twin reverb on the bench, and this is a strange one. The sound, which as described sounds like a feedback condition, did not happen when presented to me for inspection on-site. and while I think I know why, I still have to observe all safety procedures. Just in case the...

Hi everyone. I'm picking up a Yamaha RX-V870 for $12 CAD. Does anyone have any input on this device? I'm primarily going to be using it for music. Records in particular. Hooking up a Pioneer PL-255 turntable directly to it through the phono input. As well as 2 Technics 1200 turntables...

Hey folks, I’ve got an ongoing issue with my setup that I can’t seem to figure out so I thought I’d turn to the experts here at AK! The details of my gear are below but here’s an explanation of the issue: Long story short, the woofers in my speakers are violently pulsating back and forth both...

I sold Akoustic a non-audio item in BarterTown and he made it an easy, friendly, quick transaction. Highly recommended buyer. Thanks much! Nolan

I bought a McIntosh tuner this week from ajward549. Since we both live in Tennessee he agreed to meet between our cities to avoid the vulnerability (to the tuner) and expense of shipping. Thanks to Andrew for making that drive, and for making the whole transaction easy and friendly and...

Just picked up a NOS Technics SL-1210mk2. Never been used. Fitted an Ortofon SH-4 Heashell with an AT95e cart that was lying around to get it up and running but when it's powered up, with no vinyl spinning and I tap the armwand or use the armwand lock, I can hear feedback through the speakers...

I bought an Oppo universal player from N8Nagel and he made everything easy: quick and clear communication, fair price, easy terms, fast and secure shipping. Highly recommended AK seller. Thank you, Nate! Nolan

I sent him a broken Shure N97HE stylus for retipping, so I could retain the original Shure look and the good integrated brush. I got it back quickly with the diamond and cantilever I ordered (a high-quality elliptical). I'm listening to it now, very happily. So I'm reporting that needlestein...

I bought a cartridge and stylus from him. Easy transaction, quick and safe shipping, good communication. Highly recommended AKer! Nolan

Hi, Does anyone have experience with owner Steve or his team from this shop in Florida? He lists quite a bit of used gear on his website. Thanks for sharing! Cheers, S

Hey Ak I'm restoring my Acurus A250 and at the same time making some mods, this includes new starground curciut. I'm splitting input and feedbackground (now they share same ground at input), but what about D3/D6...??? I parallel a 4,7uf/470nf cap over these for lower noise, but should I also...

I noticed today that if I crank up the volume during playback on my TT I get a very low frequency hum through the speakers, almost inaudible but I can see the woofer moving like crazy. It only happens while the needle is touching the record. Is it some kind of feedback? Or some other kind of...
