help needed

I have a McIntosh C20 that has been completely restored (All caps and resistors replaced). There is an inconsistent noise coming from the unit. Noise is louder in the phono section. Noise appears about 1x per second but is inconsistent when it shows up. There is a consistent sounding noise...

I'm looking for some advice/help. The 950 was in the garage for years and looks to be in excellent shape. I used an alcohol pad on the heads capstan/pinch roller. I gave it some time to dry, popped in a tape, and let it go. It plays for a couple of seconds and stops. When I take the tape...

I recently picked up a gorgeous setup consisting of a M12 amp, CX 101 Pre-amp and TX 101 tuner. MINT in every aspect. Powered up the unit and to my dismay there was no output from the left channel. I started the normal trouble shooting of swapping speakers, cables, checking fuses, swapping...

I just picked up a really nice, clean SL-D5 turntable, with BOTH spindles. This has been taken care of well, It looks like it's worth the effort. Dust cover is in good condition, clean etc. etc. I was excited, but the seller warned me that there was a speed control issue. I thought, no problem...

Does anyone know anything about this pioneer Andrew Jones designed sp-sb23w speakerbar? It is an awesome sounding piece of equipment but it died on me ..like alot of others I have found out..I think it can be fixed just dont know Exactly how.

I have recently acquired a turntable and the switch is stuck in the off position and I am unable to turn it to on or auto. Let me know what I can do to fix this, because I want it to be a present for my girlfriend.

In starting this thread, I would like to recognize that the amount of Soundcraftsmen information on this site is amazing. Goat67, Avionic, and Geode have provided massive amounts of information/guidance in dozens of threads that I have sincerely enjoyed. I have owned Soundcraftsmen products my...

I have a JVC KD-A5 that plays tapes normally, but when I go to record onto it, from the radio or any other source, the left meter reacts normally and the right meter doesn't react unless I turn the levels past peaking compared to the left meter. The levels coming out do represent the meters, so...

I found an old amp at a thrift store in McKenzie, TN that came with two microphone mixers and a feedback controller. When I pulled the amp off the rack, the two capacitors inside had burst. They were the exact same, so I only pictured one. There's a TI-84+ for reference, but I don't remember the...

Hello All, First time poster, long time lurker. I recently bought a Pioneer SX-828 for $100 from a lady moving out of her home. She didn't know anything about it as it was her husbands and it was working "good" right up till she packed it for moving a week earlier. It was packed in the original...

I believe this cartridge is a stanton 500 gold (Let me know if im wrong). The turntable is a refurbished dual 1209. It plays great and I love it. But.. I want to get the best sound so I I balanced the tone arm, aligned the cart but I wanted to adjust the stylus force (Tracking force). So does...

Hi All, Long time stalker of the forum, mostly dabble in vintage speakers and tube headphone amps. Finally decided to recently take a plunge on a vintage Harman Kardon 930 receiver. The piece is almost in mint condition, the only issue being that it hasn't been powered on for potentially 20+...

Hey AK, I just picked up a sweet pair of BA T830 for very little, the nice old lady said they were her late husbands and hadn't been used in a while. She cleaned them constantly so there wasn't any dust damage but I could tell the woofer surrounds were crumbly. I got them home and sure enough...

Hi AudioKarma folk, This is my first time on the forum, and my first post. I have read some of the sticky posts, so I'm hoping I'm not doing too much overlapping with things-I-should-already-have-known-from-having-done-due-diligence. I have a Sherwood S-7250 CP stereo amplifier that was a gift...

Greetings all, (Note: I've added some voltage omissions from the original post) I've been working on bringing a shelved SX-650 back to life and have had great results so far thanks to several threads here dealing with the power supply boards, protection circuit etc. Thankfully this unit hadn't...

So a couple days ago i picked up this technics sa-424, a very pretty looking receiver. However, after i had set it up and got everything going, I noticed that there was little to no sound coming from the left speaker. The most sound i could get out of the left speaker was barely noticeable even...

Hello, All! This is my first post here on AK, so be gentle.. I recently picked up a minty fresh, *all original* Marantz 2230 from my local Craigslist of all places. I got her home and cranked her up..sounded great aside from a scratchy volume pot. So I figure I'll open it up, clean out the...

Need help fixing my Harmon kardon 930 twin. I was doing a recap on the pre output board and the two b+ contacts managed to connect and blew the main fuse. I have since fixed that issue, but now the unit keeps blowing the fuse. Someone please help me. Ps. I'm new to ak

hey guys, I was replacing some lamps on my 7070 and whoever initially replaced them... whooofda. I'll have pictures at the bottom. Essentially they soldered the lamp ends shut and used wires to light bulbs. I clipped them out and was putting the new ones in one at a time and clearing old...

Hello everybody, I just got a Marantz 7T(SN: 18,437) this week , its in nice shape for how much I paid for it. Maybe someone can help me across this journey of trying to restore it. I know how to solder and use the multi meter . In the past I already restored a marantz 32 with a lot of help of...

Hi pioneer experts, wondering if anyone knows of a good new power switch replacement for a pioneer sa-9900? The contacts in mine are too far worn to be saved, any advice appreciated!

Hey forum, I am very new to AK. I have a Dual 1229 with a slightly bent tonearm. Looks as though something heavy fell on it from above. There is a new old stock replacement tonearm part number 218 238, pictured, that I'm considering purchasing. It comes with the headshell and lead wires. Any...

Hello everyone, I've got an Onkyo TX-2500 receiver back home with Jamo 28 speakers. Everything worked perfect, however since a couple of weeks the speakers give a 'wobbling' sound. I realize, 'wobbling' is a vague term so I'll try to explain it in detail. After I turn on the receiver, both...
