I've just got hold of a Sonic Impact T amp and would like to know the best way to bypass/remove the volume control/pot completely. I want to control the volume by using my stepped potentiometer passive pre amp.
Basically, modify the T amp to be used as power amp.
Do I just remove the T amp 50k pot and replace it with some 50k resistors?
I don't want to start doing all the recommended input cap mods & etc yet as I want to live with original T amp sound first without it's volume control.
I know the easiest way is just to turn the T amp volume to max but and I want to achieve the cleanest, purest sound when using my passive pre amp.

Some time ago I produced a wiring diagram for this mod. However when I tried to attach it, I failed. I'll see if it works this time.
If you print the diagram off and use the devices attached to the ends of your arms, you can magically turn it the right way up.
I tried to turn it around, but I only have a free version of Adobe !

Thanks for the diagram on how to modify t- amp into a power amp. After listening to my new SI t-amp using a 12 volt 5 amp switch mode mains power supply for over a week, I prefer it over my £1000 Unison Research Simply 2 single ended tube integrated amp! This £30 plastic toy amp is outstanding value for money.
