vintage

I'm hoping someone here will be willing to help walk me through troubleshooting my receiver. I have an old Onkyo TX-1500 MKII that I found for $80 on Facebook marketplace hooked up to my vintage Sony turntable. When I first bought it, the left channel sounded staticky and was much quieter in...

Hi Everyone. First time posting here. In advance, I appreciate everyone taking the time to help. I have a Technics SA-340, with a turntable hooked up to it (+2 bookshelf speakers). I also use the AUX to plug in my iphone to listen to digital music. I'm looking to add an equalizer so I can...

Hello everyone, I just acquired a pair of Jensen 700XL horn loaded speakers working for $50, I’ve seen they sell for over $1,000 working. Is that true?! I want more info on them if that’s possible, also, can you take these grilles off? I haven’t seen a photo of them with the grilles off. Thanks...

Hello! I'm looking to buy a set of old speakers called "Radiotehnika S-90D" made in the 70's. I found a video in russian language, which, i do not understand, but the guy is making some tests and he has, what looks to me like a THD test (5:07), which i don't understand either, and frequency...

Hi AK community, My Name is Lajos and this is my first post. Your community helped me a lot with my other receiver KR-5150 in my living room, I appreciate it a lot. I was unable to resolve an issue with my new receiver Kenwood KR-3200 in my working room. I'm new to vintage audio systems, and I...

Hi all, Late last year I picked up an unusual dac. It was via a UK Ebay auction. I had no idea what it was, but I could tell from the pictures that this wasn't a low-end design. As I always do, I tried to do some pre-purchase online research. The problem was that I could find very few...

Hello all ak'ers Im new to this site and to the wonderful world of vintage audio. Was bitten by the bug a few months back when I bought my first 1973 HK 75+ quad twin. I love everything about it and just sent it out for a full recap and service. Can't wait to see how it turns out... In the mean...

Hi folks, I'm brand new here and am thoroughly humbled by this forum's wealth of knowledge and kind spirit. I'm not by any means an audiophile, nor do I have a huge desire to dive very deep on fixing this unit. BUT, I do have a masochistic tendency to not throw anything away, and I really enjoy...

Hey everyone… I’m pretty new to the site and I’m looking for info on my Harman Kardon 50+. I bought this receiver for $100 locally in Chicago. It’s in really good condition and it sounds great. It’s also quad. But I can’t seem to find any info on it. There’s a hifi engine forum on it but that’s...

Full Album - including videos, documentation This unit originally belonged to my great uncle and was purchased in January 1960 for about $300. I inherited it rather than let it go to the dump last year, since I have a friend with the skills to take on a project of this scope. My buddy did all...

Hello AK'ers. I'm working on a beautiful 4430 unit. Promblems: When playing in MONO, left and right speakers sound (and sound amazing IMO) BUT when playing STEREO no sound... Well a Lot of noise and a very very low music volumen. I think someone tried to repair it before, but left a mess with...

I am in the process of putting together systems based on decade from the 70s, 80s, 90s, 00s, and 10s. It has been a lot of fun researching and hunting down equipment. I would like some input on the 80s system. A while back, I picked up a set of DCM TF500 speakers, which have really impressed me...

I have little to no knowledge of on line auctions and specialty audio websites, other than this one of course:). I like to tinker sometimes and would be interested in monitoring such sites to see if i could find some hard to find items for some gear repair projects. Looking for some guidance...

Okay, so I have 1970's era Sansui 5000 amp, 8000 rear amp, Akai tape deck and other same era stuff. Works great in my man cave. Loud, crisp and awesome, amazingly, even with tapes that I recorded off vinyl back then. I have a gazebo that I built out back with hot tub and speakers, and I'm...

Hello! I thought i d share my ongoing restoration on this wonderful integrated amp. First impressions; quite modular and easy to work on since many of the modules are plug-in! the amp is in decent shape apart from the bass and balance sliders which at some point snapped and have the metal part...

Hello AKérs I´m really curious about using a vintage unit ONLY to listen it with headphones. Is it a good idea? Could the long term use of headphones damage a vintage unit? A friend on mine (not suscribed to this forum) asked about this. what i know: headphones in the unit are only for...

I decided to recreate this PCB. Most probably they use this one in other Marantz models, that I'm not aware of... In the first place, I made a clean copy of the schematic (with the vintage look preserved, of course ;)): Then, when I was working with the PCB, decided to add an option for...

A while back my lovely wife found a nice little toy at a local thrift shop so I got her to bring it home (love that she gives me a call when she sees something nice). Was really needing a nice little project to keep me occupied with Omicron raging out there these days. Ordered a Deluxe...

This took a while to type :cool: Hi, I'm looking to add more songs to my mp3 collection. I particularly enjoy the use of double bass featured in the majority of my mp3 collection, so I'd like to find more songs featuring double bass. I tend to listen to Country, Folk, Rock n' Roll, Rockabilly...

So, Ive gotten my hands on a pair of 1968 klh model 12 speakers. I got them in working condition but unrestored. Used them for about a year until it became apparent that they had deteriorated a bit. Im awaiting the parts for a full restore of the boxes, my only remaining issue is that one of the...

Here are the steps I took to build these wood cases: After exhaustive searches of the interweb I found only one relatively complete guide on how to build nice wooden cases for vintage (or modern) audio receivers. And now I can't even find that one anymore. So in case there are other fools out...

A few months ago I was driving down my street and saw a bunch of stuff set out on the curb, as I passed by I saw the gleam of a few tubes catch the sun, my heart skipped a beat and I immediately slammed on the brakes! Turns out the guy down the street had ripped a Nutone 2400 intercom system...

Our Pioneer SX1050 is in some need of TLC. Does anyone know of a reputable audio repair shop in the Phoenix area? Our heart is aching we may also need to take our JBL's in as well.. Please help

Moderately loud volume, fed from an Audioquest Dragonfly Red off my iMac Pro... my old NAD 2140 amp cuts out on the right channel after a couple minutes. Happens with or without the soft clipping engaged. Output is very good, clean, not overly loud. Via ELAC Debut 6.0 DB62 speakers, rated 6...

Hi folks Have started in earnest to attempt repairing a Yamaha CR-2020 that was completely dead. Started with the obvious Power Supply board issues that I have seen posted on YouTube and decided to start with a full electrolytic recap (except the large filter caps) of the Power Supply Board and...
