switch box

I have 3 turntables in my set up ate the moment. 2 of which are currently using low output mc carts. I have been having trouble with noise introduced by the switch box I use for a bit now. I currently have a sony sb-700 switch box because most of my setup is sony stuff and figured it was a fun...

About 30 years ago I had a "Guy" who fixed my MC240, and he built a switch box for the amp (see below pics). Turn on righthand switch: both outlets received power. Once the 150W bulb became fully bright, turn on left switch: bulb turned off, all power to MC240. I took his word that this was good...

I have 3 recording devices (a Nak Cassette 2, a Nak 550, and a RaspberryPI ADC ) which need to be connected in different combinations to a NAK Receiver 2 - the one with a single Tape in and out. It appears that what I need to do can be done with any of the boxes listed in the title. The Akai...

Hi everyone, I need your help in solving my problem. I have 2 integrated amps, a new Marantz PM 6007 and an old Dynaco SCA 35 tube amp. I have 1 pair of speakers. Right now I have everything hooked up to the Marantz: turntable, CD player, tuner and Bluetooth receiver. Question: is there a switch...

I've come across an input problem in my system, but one which can't just be solved by a normal line input switcher. I have 3 tape machines: a Nakamichi BX-300, H/K CD-491, and a Teac A-6100. I currently run an SX-939 with my Nak going into tape loop 1 and my Teac r2r machine into tape loop 2...

I want to share a single set of speakers between my Yamaha CR-1000 and a Pioneer VSX-32. I want to build a switch box for them. I've noticed while shopping for switches and relays (I haven't quite decided which way I want to go) that the prices increase exponentially with the current rating...

Hi. I'm curious. Does anyone manufacture a selector switch box specifically designed for turntables, multiple turntables? A separate component as a hub for individual turntables, even when using a phono preamp, with or without ground wires, and RCA interconnects/cables/jacks. Similar to a A/V...

I'm interested in building an RCA switch box. I'm technically inclined but have never done anything like this so I don't know the technical details of what is a good or bad idea as far as sound quality, and the best way to achieve this schematically. I have multiple sources, let's say 2...

I've searched a number of threads and posts on the topic of using two receivers with the same speakers and before I pull the trigger on a solution I wanted to get some expert advice. Objective: what I want to do is have the ability to use and existing A and B speaker set for either a Sansui...

Need extra inputs on my receiver. I found a number of RCA switch boxes, but they're pretty ugly. Is there anything that looks like a stereo component and doesn't cost a fortune?

I've seen articles on how to build RCA switch-boxes with a rotating switch, but nothing on how to build one with pushbuttons. I've seen pre-made models on Amazon, although those are invariably built to handle composite audio for TV's, so I suspect that they are of inferior quality. Does anyone...

How this for DIY ? I have a nightmare of RCA cables running every where on the back of the stereo rack. My hands and eyes are getting old and I find it very difficult to work the cables when make a change in connections. I've considered a consumer grade RCA switch box as solution but even...
