Hello!
I’m newer to fixing record players and this is my first time trying to troubleshoot a linear player, looking for some advice .
it’s a weird problem im trying to figure out , power indicator lights up , but will not respond to any buttons pushed.
At first I thought it was a problem with...
My dad has a pair of Infinity RS6s from forever ago. I imagine they'd sound decent if it wasn't for the ring of foam around the 8'' woofer dry rotting. I've begun to take the speaker apart to re-foam or replace the woofer entirely (depending on which is cheaper and yields better results), but...
I ask for advice, dear inhabitants of the forum. I bought this turntable today, it looks great, but the motor won’t start. The power cord is not broken, voltage is supplied to the motor terminals. The lower bearing is lubricated, but the motor does not work.
Hey! I'm getting a wondering bias voltage across pins J708 & J710 (bias voltage). Its causing some annoying static and I'm not sure where I should look first. The unit has been re-capped and sounds great for the first hour, but eventually the bias fluctuates on the left channel and it throws the...
Hey what's going on? so when I play music through the amp the left channel is distorted the right channel is clear. when I moved the amp, both channels went completely distorted and I had to unplug it, loud buzzing through the speakers and buzzing around the bad darlington area. I pulled the...
This is my first time posting to the forums ever! I am kind of newer to this stuff, came into possession of a couple components and speakers a bit ago and just bought more stuff today.
I bought a Technics tape deck today, it plays tapes really well but it doesn't properly rewind or fast...
Hey all.
I'm usually a Kenwood addict, but I am pretty new to the repair/resto hobby (this will be the 2nd amplifier I've worked on...) and have been looking for a new project to tinker around with. With the graciousness of @eiraved, earlier this week I received an A-700 in need of some love...
Hello. I posted this in two incorrect spots first so hopefully I found the right board lol
I own a Pioneer VSX-501 that was given to me by my uncle years ago. I use it in my living room for television audio and as a general purpose multimedia player and it's worked...
Hello AK users, I'm still working through my Nikko QSR-4040 quadraphonic receiver. I have gone through it; replaced caps, bulbs, cleaned controls twice, etc. However, when I got the unit it had bad bass distortion on both front channels, the rear mimics front in 2CH. I'll do more thorough...
So long story short, last summer I tripped over a headphone cable, destroying both the headphone plug, cable, and the amp's jack. I was able to repair everything involved in the crash, using some krazy glue and baking soda to get the plastic housing back together. As you can see in the pics, the...
Trying to fix this speaker. Both drivers are working (tested them by holding the audio cable from my receiver directly to the contacts on the drivers) so i think there is a short on the pcb board. I know very little about electronics so it's hard for me to follow the path of current. I tried...

Good News: I got a free Technics SL-1700 mk2
Bad News: because the ebay seller shipped it loose in a box without a scrap of packaging and without the tonearm secured
Good News: The platter didn't come loose and still spins quietly at the right speed.
Bad News: The tonearm makes a creaking noise...
Anyone know of any audio repair technicians near Nashville? I used Hi-Tech Service a few times but they closed a couple years ago. I have an SX-1250 that I'd like to get restored.
Thanks,
Chad
Hi everyone
While I was walking my dogs I came across a Boston G2 subwoofer speaker for car audio at the park. Someone most have taken it off from their car and dumped it. So I took it home not just to keep the parks clean (I find all kinds of stuff when I walk my dogs, it is amazing, some at...
Welcome guys,
i am reparing my Sansui 9900Z. I bought this Reciever some years ago on Ebay.
On Power Amp. Board all drivers (Q7-Q11) and power transistors (Q1-Q4) were burned.
Q12 and Q13 were fine, just like "kQFT1" (JFET x2).
I decided to change all of them here is the list:
Q1 2SC3858
Q2...
Speakers: definitive technology bp-20 with bp-30 woofers. 6ohm impedance 500w max.
Amp: adcom gfa 5500 200w/ch @8ohms
Hey all, I ran into an issue today after sitting down to have a listening session. About halfway through a song that's pretty heavy on the bass, two of the mid-range drivers on...
Just wanted to share my success story and pat myself on the back a little. (WARNING: BAD SOLDERING AHEAD :rflmao: )
About 2 weeks ago, I took a closer interest in how my equipment works, so I bought a digital multimeter and started studying various threads about schematics, how electrical...
Hello, I am trying to repair a DBX 3BX Series I (revision 2, the one without the daughter boards).
Some things I managed to fix but I still have a problem with the MF circuit. As soon as I raise the expansion, no matter the transition level, the output goes up as you can see in this video...
After a long time where I was no longer active here I would like to throw an interesting project into the room and maybe someone can help me.
Normally I mainly deal with Yamaha devices but for once a NAD Model 300 has found its way onto my desk.;):biggrin:
There was a note on the lid...
Love my old AX but the left channel sounds slightly "dull" compared to right channel. At first I thought it was just a volume difference, but it also lacks some brilliance compared to the other channel. Sitting at ideal listening position, the right channel sounds brighter and louder.
I have...
Hello! Been a member for a long while, but haven't been on in a very long time.
I have the full Heathkit Professional set w/AA-1800 amplifier and a DUAL turntable.
Does anyone know of a place somewhere within a few hours drive of Knoxville, TN (or The Villages, FL) where I can take the various...
Hi,
I bought a Pioneer SX 727. I noticed two things. One, the bass knob doesn’t go full power, it goes only 3/4s of the way. In addition, whenever i turn from fm to phono or other, there is quite a loud static noise.
I opened up my Mitsubishi DA-A30 to set the idle current and center potential adjustment and immediately noticed some heat stress marks on one of the PCB boards (CTL-56).
It appears that the heat stress is right underneath two 820ohm 2W resistors R313 & R314
No other part of any other board...
Hello!
I want to learn to repair reel-to-reel, pick-up and amplituners.
I have a minimal knowlegde about electronics. I tried to search on the web for useful materials but I am only able to find some general electronics documentation.
If anyone knows some books, courses, tutorials, please...
