hey every one im very new in this topic, ive think that i have found the solution to my stereo amp dream.
i have tried to build a passive one but after my pedals it seems to have lost all the input from the guitars and are simply useless.
therefor i read in here that a buffered aby switch whould be better and most of the time if build right hum less.
ive found this scheamatic http://www.geofex.com/FX_images/TransformerSplitter.pdf
but i have 2 question how to @#$%inue
1. is this that i only use half of the lm833 circut, meaning connecting to indput 1 pin 2 for + and pin 3 for - and then 1 output for the output

2. i now the (Mouser
42TM018 is a 6 pin. but how do i connect it is it in series. so like it does on the picture

really hope someone have the time to teach a newbie like me some basic stuff, thx in advance good building out there
OF COURSE I MEANT PIN 2- AND PIN 3+
I actually haven't seen that schematic before. But I'm sure there are other more simple splitter circuits around (no knock on you RG!)
To answer your questions;
1: Yup, you got it
2: The rating for both the primary and secondary are 10k ohms so I believe you should just leave the center-tap pins unconnected.
You realize, of course, that it's a bipolar (+/- 9V) supply circuit.. :icon_wink:
q1)
maybe use an LM386, it saves you getting a Dual supply (both +9v and -9v), you can get a simple single supply, (only +9v)
the easy thing is that they have ground referenced inputs, but an output at mid-level bias (+4.5v offset)

q2)
Kevin already answered this adequately.
cheers, Iain
This does it all very simply, but it would mean scrapping what you're doing and getting JFETs. You can use the transformers in other projects, tho :)
Not passive; fits the 'buffered' concept. Just another view on what you're doing.
Hope that helps, welcome to the forum!
