hi there, I came across one of these in a music store for $15.. but it was diagnosed that it needs a new belt. I know this might not be all that's wrong with it but if that IS all that's wrong with it, I'd be willing to buy that and open it up, but my question is does anyone know where I...

Hi all, Looking for some help here... I have a digital piano Yamaha YDP-163 which has 2 headphone jacks as audio outputs. Sadly, no AUX OUT or LINE OUT jacks so only headphones. When plugging a single pair of headphones to either of the headphone jacks, the audio signal is clean, clear and loud...

Hey guys, instead of calling it bad luck, im calling it an opportunity to learn. I scooped one of those "beginner all in one" guitar / amp kits a couple days ago, where the whole thing is in a box, with picks ect ect. It's a first act brand and was $85 total. The guitar is surprisingly...

Hi guys, Here is a new mic shoutout that includes 3 products from microphone-parts.com I had many questions about the mods and the DIY Kits. Hope you can hear the subtle differences. I'm still getting used to audio and video productions so your comments are needed and welcome. Btw, I'm not...

I have a GS 3000 console turn of the century stuff. The Mute mpu board has gone out part 002-347-1 so all the mutes seem stuck off and mute and status leds are stuck on. No LCD. Everything else works. Need to find a replacement or figure out how to fix it. The pcb makes use of a P80C32 40 pin...

Does any one have Bin likes for Studer A807 mk 1, current version installed was 40/87, but can change to later version if available. D

Greetings- I recently bought an older Shure 545 (4-pin Amphenol era) on eBay, and while it works, it sounds a bit of the dog with voice: a greatly diminished low end, and reminiscent of talking through a paper towel tube. Given there's only three parts to the mic: cartridge, transformed and...

I want to break a signal path which has no discrete components in it as of now. I want a 3 position toggle switch to have the options of Stock (signal pass through), Resistor 1 (signal path broken and routed into Resistor 1), and Resistor 2 (signal path broken and routed into Resistor 2). I've...

Hi there! I have a dbx 386 dual channel tube preamp. It was out of service for some time and when I recently put it back in the rack only a couple of LEDs turn on. On inspection it seems that the larger of the two transformers supplying power to the PCB has transformed into a Gandalf No-Pass...

Hi guys, Like the title says, I got one of my two LA-610 who doesn't compress anymore.. the action faded over a few months. I tried to change the tubes and even exchanged the opto cell with the other LA-610 and it did no good. So I guess a cap or a resistor failed.. I'd need some guidance...

Edited for clarity. So, I am setting up for some hybrid mixing for the first time and have db25 connected from the analog out of my converters to the input of my radial lunchbox. The lunch box has preamps for recording as well as an eq. I accidentally sent phantom to the analog out of my...

Well a few of you already know I was working on this project I'm gonna do a few more video on the product with more compare tests with other mics. Thanks for any comments or questions Build and presentation of the DIY T47 mic from microphone-parts.com - YouTube by pcrecord posted Jun 12, 2016...

just saw this on the SOS YouTube channel, from AES NY, happening this weekend. Looks really cool!

@Boswell or any of our other resident electronics wizards.. I have this ADK AP1 mic pre that I love, but it lacks metering. There is nothing there to indicate what my input/output levels are. I'm wondering how easy it would be to attach a meter, even a simple VU, that could help me...

hey all, I'm pretty new to this section of RO and at a beginner level as far as understanding of electronics. I've become progressively more interested in the creative sonic options there are available thru electronics modifications and repair. Anyway my goal is to within the first year to...

Hey all - I have a Lindell 503 power chassis. I have been using a Phoenix DRS1R Preamp in the first slot for about 5 months now, no issues. I recently got an A designs P1 as well. All was fine, then after a couple days, I got allot of electrical hum happening, much above the noise floor of the...

Hi everyone, I'm not an audio engineer or even sure what one is but I have a problem with a humm. It happens when ever I have some audio device connected to the wall outlet. Let me explain further and see if one of you gurus sees how to fix it or at least track down the problem: I have a Sony...

is it possible to change levels between -10 and +4 with transformers?
