Are you aware that the voltages in a tube pre are lethal? Just letting you know.
Adding a Pre-Out to an integrated tube amp
I've got two sub amps with line level only inputs and a Melody I880 integrated amp with no pre-out. So I want to add a pre-out for the sub amps. Two amps so need L/R not summed to mono. Being a tube amp everything is easily accessible and first thought was take right off from the volume. But then doing some research saw people recommend using an op-amp or resistor, and some others saying you need a schematic to take the signal after the pre-amp stage but before the amp. Seems to me line level should be enough, ie right off the volume will be okay, but will it? Anyone done this and know what will work?

millercarbon, Please simplify your life and buy 2 Dayton Audio SA1000 sub amps. You'll save yourself hours of aggravation and possibly electrocution. The best new price I found is $409 each on Amazon. However, I came across this shop in St. Louis selling 2 used for $600. https://reverb.com/item/6598543-2-dayton-sa1000-home-theater-subwoofer-amplifiers It's on the Reverb site and the ad states the seller is temporarily away. But this looks like a very good deal worth waiting for and you can message the seller. Tim |
That's exactly what I have. The Dayton accepts line level inputs only. My options are add a pre out or use a Line Out Converter to drop speaker level down to line level. That's what I've been doing with my current sub which has a plate amp that accepts speaker level. The Dayton's don't and I thought adding a pre-out might be easier/better but maybe not. Checking around it seems the right LOC might be the way to go. They look kinda tacky but if it works I could hard wire it inside using existing unused RCAs which would be an improvement on the cheap ones on the LOC and look a lot better too. |
