channel

Hello, left channel is distorted at any volume. Found the emitter resistors to be brittle and cracked. I have a mouser cart to be filled. Any other known 400 issues? For now I've ordered 2. New pc-28 boards but if I can fix with a few mouser parts, I'd save $170. Which I'd prefer. Thanks yall.

My SX770 has a hissing noise only heard on the preamp RCA out on the left channel. It is the same volume regardless of how loud the volume is turned, and is present regardless of which input is selected. Any idea which transistor may be the culprit? Everything else works perfectly.

Hi, My Sony STR-K1900P receiver started having sound distortion on all the speakers, no matter what source I use - TV or radio. Here is the schema of the main board, any suggestions? Thanks

Above is from an old post. His description accurately describes my problem. Looks like the OP did not get much action - LOL I have the same problem. It was working fine last week. I tried to play an album last night and the left channel was shot. I only had time to test a few things. I switched...

Greetings AK, I am losing the right channel input before the pre(PE01) regardless of input(PHONO, FM, AUX). The unit was recapped/restored, including replacing broken Pre and Main RCA inputs in the rear, recapped Power Supply(P800), Phono(P400), Buffer Amp PH01, Dolby-Tone-Meter(PL01)...

I bought this pioneer cassette deck recently and today I spent basically 4 hours having to rebuild the entire mechanism. Now I have it mostly working except for rewind which works but is kinda slow. Regardless it suddenly decided that it only wanted to output to the right channel even though it...

Hey guys, and girls ofc :) Recently started learning how to repair faulty amplifiers. My very first project was a Peavey CS 1000 Power Amp that i purchased off ebay. Took me a while to get to grips with what im doing, But i eventually figured it out... But to cut a long story short.. The amp...

Greetings Kenwood crew. I recently bought a stack of Kenwood components and have been enjoying getting things running and starting my hi fi audio journey. Here are my components: KA-127 Stereo Integrated Amp - 125 watt peak output - 8 to 16 ohms - A and B channels with L and R each for total...

I am hoping for some advice on my MC 2105 that's not functioning correctly. The right channel suddenly became extremely quiet. Abnormally quiet. When the volume is turned way up on that channel you can hear the music but it's extremely distorted and very, very quiet. The left channel is...

Hello, I have a problem with my trusty Marantz PM-68 which I use now as a secondary amp for my DAC connected to PC in my office. I've been getting problems with right channel getting quieter and overall sound degrading in last few weeks with slightly crackling/hissing sound in both channels...

Hi all, I have a question. When I turn on my Harman Kardon citation 16a amplifier the left channel comes on faintly amd after 10 minutes or so is up to normal amd same as the right channel. I don’t recall this doing that before so something g has definitely changed. Any one have any ideas...

Hi all, So I have a Kenwood KA-7100 amp. I bought it fairly recently from a guy who swore that all the cleaning, etc, had been done. Just the other day I realized that the volume is starting to go (it's a bit less and perhaps slightly distorted) on the right channel. I am a total non-techie...

Hey Everyone, I picked up a Sherwood S-7200 for a nice $20. The AUX 1 and AUX 2 work just fine with output of both speaker channels and all AFTER replacing a speaker fuse. However, the Right channel is extremely weak and humming on FM / AM / Phono inputs. Loving the sound of this on the AUX...

I have 2 marantz 2235b systems that both do the same. The issue: the right channel on the main, backup/remote and headphones stops working after about 10 minutes (sometimes longer). If I turn the volume very high, the right speaker crackles and then starts working again. I have noticed...

Hello from Estonia! Hope you are all well. Got my hands on this really sweet '77 year Kenwood amp. Unfortunately left channel is dead. I really like this amp, so I would like to repair and restore it. Hopefully you can give some little guidance needed to bring this amp back to life. Before I...

Was reluctant to post anything but i'm at a loss. I've done a bunch of reading here already and understand what may be the culprit but I could use a little guidance. I have crackling coming from the left channel of this 2230. It is not the speaker because I've swapped speaker connections. I...

Hi the AK community , i'm joining you with a really good Technics SL-V5 , in an amazing condition. But once arrived at home, after setting it ; just realised that the Right Channel Output is weak. The Left one is amazing, by the way. I tried to find the manual to follow some instructions in a...

Hi Guys, I recapped the pre-amp board (PE01) on my 2325 and am not getting any output on the left channel. I am running a sine wave from an audio generator into the AUX RCA inputs and am monitoring through the headphones and Tektronix 465. I am only getting output on the right channel in the...

THE INCIDENT I was listening to XM Radio over the AUX input when I heard the audio fluctuate. I thought maybe there had been a power spike (despite being plugged into a surge protector). Suddenly the right channel became very weak and garbled. Occasionally it would break back through to full...

Hello All, Don't know a whole lot about these machines, but I do know I've recorded on this unit previously so it did work fine at some point, and I didn't 'adjust' anything. After a year of hardly much use, I tried to record and noticed a problem. Playback is missing the right channel (it...

Symptom: Left channel is distorted, but only when the speakers are selected and connected. Test 1 settings: Headphones plugged in; 8 ohm speakers connected to Main speaker terminals. Speaker knob to Remote / Off: No distortion through headphone left channel Speaker knob to Main / Both...

I've suddenly started hearing a crackling/static noise in one channel of my Fisher X-202 integrated amplifier Description: - sound is an uneven "crackling/static" noise, NOT smooth white noise - in the right channel only - not too loud, however loud enough to be heard in a quiet room once music...

Hello everyone. I've been reading these forums for a while, ever since I picked up a dirty SX-650 for 35 euro (~40 USD) a couple of months ago. I've no experience working on amps but was hoping to get into the hobby since I love the look and sound of vintage audio gear, so I took my chances. The...

Greetings, fellow stereo curators! I need some assistance from you today regarding high DC voltage on the left channel in our beloved STA-78 receiver. Dad bought it new in the late 70s and passed it on to me, but when he tried using it this summer in our garage it let out the magic smoke after...

Ugh. I have an old Pioneer SX 880 that is sick and The speaker channels are out of sync volume wise and balance must be constantly adjusted in parallel. The Left channel has WAY more bass the the right. Probably too a fault although the right can use a little more, sounds very dry...
