Ok, I'm going to make a stereo IGC with the following features....
-stereo out
-3 inputs
-volume control
-front power button
-front source selector button
Implimentation...
-RCA Inputs
-Discreet Transistor Buffer as shown on Decibal Dungeon w/ BC547 transistors
-- Question: Should I buy a bunch of these transistors and run a test circuit to find the 3 best matches?
-Big input caps, I'm thinking 4.7uF solen poly's
-alps blue 50k log pot for volume
-Analog SSM2404S to control audio switch
-Wood Casing with copper foil for shielding of signals
-320VA 22+22 secondary torroid transformer from parts express
-Quantum Research QT110 capacitive buttons for front panel (to keep a nice clean front) through wood
--1 button per input
--Single Power Button to turn off and on
-Led's behind power knob glow when the amp is on, letting light leak out from behind the volume knob.
-Passive Heatsinks with slots in bottom of casing to vent heat
-Soft Power on (delay) to minimize power on thump and buzz
-Discreet Rectifier bridge
-Snubberized Power Supply
-Seperate power supply & small shielded transformer for logic chips
-Seperate power supply for buffer (fed off main torroid)
-Shielded Input Line Filter (inductors, caps, and resistors)
-------
These are just ideas I've been plinking around with. If you have any recommendations let me know. Also just so you know, the first pair of speakers this amp will see (other than my disposable crappy test set) are a pair of Paradigm Atom v.3's. So the load is pretty easy, but I want to make this amp power most speakers.
Question: Is there any merit to the T-Feedback setup? I read about it, but there isn't too much talk on it.
Question: Can I just setup my pot in front of my buffer as I normally would?
