    No sound coming from NAD 712

    Hello! I have a NAD 712 that I have set up but there is no sound coming out of the speakers. ): No matter what input I use there is no sound. The monitor light is not on, so it isn't that, and the connectors between the pre out and main in are there, so it isn't that either. It also isn't the...

    I just picked myself up a pair of Empire Grenadier 6000's and I don't know what I need to do with them. (Help!)

    Hey everyone, Millennial here that unfortunately doesn't know a thing about audio or vintage audio for that matter at all. I love these end tables, and I know that I want to make them work into speakers. I just haven't the slightest clue where to begin. I keep hearing that these are "passive"...

    Hello everyone! First time posting here. I've read many threads and after not being able to get help elsewhere, I've created an account and am now posting here. To keep it short and simple, I bought an amplifier, brand Akai, model AM-35 (apparently it was sold in the UK and Germany). It sounds...

    Record player arm won’t lift but can move side to side.

    I recently got my first record player( DC servo automatic turntable SLBD20B) for free, but the guy that gave it to me said it needs a new needle, and the arm won’t lift. When I place it on the record it sounds pretty bad but I think the needle might fix it. Once it reaches the end of the...

    Massive pain to remove an IC?

    So I don't really know where to post this but I bought a hp oscilloscope and it needed a new battery for the memory chip. I ordered a new chip and figured I'd remove the chip before the new one arrived. I kid you not I must have spent 2 hours just trying to get the thing out. I was fairly...

    denon sa-3900 service manual and questions about caps.

    I have a denon sa-3900 amplifier that is quieter in one of the channels. I have thoroughly cleaned the switches and pots but that doesn't seem to be the issue. I have been pulling all the electrolytic capacitors of the board to check them but most seem to be within 20% of their rated value. So...

    Now no left channel at all

    Long story short, was using a crap soldering iron and the joints weren't great. Randomly the left channel stopped working. I got a better one, changed the rca port and soldered everything together, but now there's still no left channel. I've switched RCAs on the receiver and pretty much isolated...

    b&w dm4 issue where volume at certain frequencies is lower relative to the rest.

    I made a post about an issue with a dm4 set a bit ago but due to the issues with searching I have been unable to find it so I apologize for opening a new thread. Previously I had an issue with the woofer rattling but that seems to be fixed as I noticed that the rubber ring on the woofer was...

    OG Refreshing His OG with New Tech, Stumbling Some...

    I said stumble, not "fallen and I can't get up". Also, OG for the subject: Old Goat/Old Gear. Here's the deal, it's two-fold really. 1. I have loads of time. 2. Even though #1 sounds good, I'm on a fixed income so budget takes priority. First, it seems search is not working on the site...

    B&W dm4 speaker rattle, crackling noise at specific moments only?

    So I know next to nothing about speakers. I have a pair of dm4s that I haven't looked at for years. Today I tried them and noticed that one of the speakers sounds kinda rattly at certain points. I also feel like the volume drops at times but I cannot confirm this. I also find it very hard to...

    Best vintage turntable under 600 usd with auto stop?

    I recently had to sell my ps-x75 and while I am looking for a different one where I live they are really hard to find. So I was wondering what a good option would be for use in the mean time. It needs to have an auto stop and I would prefer if it was not a mechanical mechanism. Extra points if...

    Are covers necessary for tube amp /receivers?

    Hello: This is a total newbie question… I am just now trying to get into collecting vintage audio gear, including receivers. There is a Harmon receiver (TA 260) on sale nearby. However, it doesn’t have a cover (cabinet). Would it be smart to purchase this with no wood cover? Are covers...

    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.
