I got this amplifier a while ago and I noticed that the fuse on one of the channels was blown (I think it's the right one). I measured the output transistors and the ones for the defective channel where shorted. I ordered some new ones and installed them (for both channels since I read online...

Hi, I apologize for this already now but I am newly diagnosed with hi-fi and I am a bit of a technical idiot. I just got a H/K citation 11 and 12 and wonder how I need to connect them? The 11 has a cable coming out that is open at the end with 4 cables. Red, white, black and green. Please help...

Hello, A few months ago I retrieved my Luxman l-80v from storage. After connecting it up it started humming aggressively so I turned it off and let it rest for a bit. On the second attempt, the humming grew and the old 50v 10000uf Capacitors exploded. All 3 of the 0.3A 250v 6x30mm fuses were...

Hello all, Apologies in advance if this is 1: not the appropriate place to post this and 2: these issues are commonplace and have been answered elsewhere. I got 1972 Pioneer PL10 and the audio quality is full of static and is of overall of poor quality. I am a complete beginner in the world of...

I have made a post about this before but sadly did not receive any replies. I have a fairly simple direct drive turntable made by yamaha. However it doesn't spin. I replaced the caps and tested all the other parts in the circuit but to no avail. I think it probably has something to do with the...

On my Sansui 350a, I only had an input connected to the aux ports, but accidently left the selector on phono. When I started to play music, I could hear the aux input, very faintly and noisily. Selecting aux played my input like normal. Is this just harmless, but interesting, interference? I...

Ok so before anything else I want to mention that I am not talking about the ground hum. I have this turntable that needed a new phono cable. However I didn't really have any cables laying around at the moment so I made my own. But now if the cable is plugged in and the position shifts slightly...

Hello! I recaped a 790 sansui, don't working before recap. Now relay clicks, DBT show no shortcut, unit sounds Bad and once the volumen reaches 35-40%, distorsion is really Bad and finally relays click and sound go out. Dc offset is ok, about 3+5 mv, but bias is 45V!!!! On test point 5-6 & 5-7...

See title. Is this normal ? And if not is it easy to solve? I would prefer keeping it as is as it was completely overhauled a few years ago. But since it's not mine I don't know if this has always been the case.

Hello, I have had this turntable stopped for months because it wasn't working properly, but I have now manage to make it work and play a vinyl, until I realised that at the end of the vinyl it did lift the tone arm until it reached the label of the vinyl record. I had another look around the...

Hello AK'ers Hope all of You have had a great new year. For me a very special gift by myself, a 6350q un good shape, but not working. Well, the motor is stuck, can't be turn the shaft even by hand, according previous owner, the TT was misstreated by carrier (Fedex) and it has a hit in the...

I found an old sansui transistor amp and it has a weird issue. It seems to be working but only after turning on or off. It gets to the correct volume for a second before going to a very low volume, however the signal isn't distorted. If I keep switching the amp on and off quickly it keeps...

Hello everyone I'm a complete novice with tech repair but eager to learn, I've recently inherited a Sony TC-K661S that's been sat in a loft for a few years, I've hoovered out a huge buildup of dust and given the inside (of the bit where the tape goes in) a wipe round with isopropyl. I've tested...

APOLOGIES POSTED THIS IN THE WONG SPOT

So I’ve been trying to do some research into Design Acoustics PS-5s and if they had an accompanying floor speaker/ woofer. My old man used to have a floor speaker that had the same wood and brown grill cloth look as the PS-5s, I’m just unsure of the model. He had gotten rid of it years ago...

Hi there First off, I'm gonna be honest, I don't know much about Hi-Fi and thought this would be a good place to ask for advice :) I recently modified my 2-story bed to fit another mattress below it. And now I am going to install a monitor (the one in the picture is a temporary one) in front of...

I have a teac c-3 cassette deck that doesn't seem to be responding to any of the mechanism control buttons. I think it might have to do with it not recognizing that a cassette is inserted but the problem is I am not entirely sure how it detects this in the first place. Can anyone who has a...

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...

According to the previous owner it was working but suddenly they could hear pops from time to time via the speakers until one day there was a very loud pop and it stopped functioning properly. I tested it and it seems like the problem is limited to the pre amp as the power amp is working fine if...

Merry Christmas AK'ers! I could use a little help solving a blown fuse problem on a SX-727. This unit was my first recap project, done 4 years ago. Following AK threads I bravely dug into a SX-727 to recap it, but little did I know how hard/easy it was! I figured even if it blew up it could...

Hey all, My dad had a nice Mitsubishi Hifi setup from the late 70s. A few years ago he had a technician from some company in the city come in and get it working again. We’ll let’s just say he didn’t do the greatest of jobs (he stole the matching cassette deck, said it was broken and gave us...

Greetings! I recently picked up a Sony PS-5520 turntable and need to start a forum to help me bring it back to life. My initial question has to do with the corky saw dust like spring cushions that go under the inner compression springs. Sony's part number for the spring is 4-804-634-11 and the...

Hello, I am hoping someone might be able to assist me in identifying the Westinghouse player in the photos. It looks a lot like a Westinghouse Rainbow Toner but the face appears to be more up to date and more of a replica of older models. Also, you will see that it is missing dials and knobs...

Hi there, I've got my hands on a Sony SQA-100 Decoder/Amplifier and as someone who is new to audio equipment I'm looking for advice on how exactly to use it and what it's actually supposed to do. Can someone tell me how much use is this piece of equipment is to me if I wish to use it as a...

Hello everyone. Recently I came across a seller that is offering a pioneer spec 1 for a fair price in an ideal condition. I love the piece, but researching a bit around I found that it needs a spec 2 or 4, or an equipment with pre out/in, in order to work. I looked at My equipment and didn't...
