been working on this for weeks, think I got it, then I don't like the way it works, also some speakers don't work on a , b or both some speakers on sometimes, and then on with all
still have to find out how to hook up equalizer and subwoofer if I can to this old Planar XR4120 FOUR/2-channel BRIDGED RECEIVER????
I DO NOT KNOW HOW TO TRANSFER FROM ANDROID CELL TO THIS CHROMEBOOK SO NO PHOTOS UNLESS I CAN SEND TO MAIL OR SOMETHING
 
The Solid State subforum is for questions about amplifiers that use transistors.

Is this your amp?

i hope this is not too long a post for here>What are you doing with my amp? lol yes it is... so that is what i need help with setting up all my components to it, to work together... a channel b channel both on both the 2ch and 4 channel settings. How to add or hook up speakers on it so that they work on all ... can i add an equalizer and a non-powered sub woofer? i have added my CD player and my two turntables, and a reel-to-reel. So what settings do i need to be on? What are those metal U-clamps that are plugged into the main in and preamp out? i have Y RCA adapters. i have wired,,then to RCA plug... to add extras where there are not enough jacks, if that helps
 
Yes i will later today it will have on the main and remotes speaker wires I know have connected as now at least I have sound but it maybe wrong set up as it is one positive to a neg of other block music comes out louder than if it is pos to neg from one block to another I do not get any thing working on all channels if I put pos red and neg black together on main side.. or am I to use the immediate block to the bottom instead of to the remotes<<<<<<<<I also want to say thank you for all your help up to this point I am in wow this is a very helpful person..
