Make a preamp with an already buil amplifier
Can you help me to take the audio signal in my amplifier to an output RCA for just
préamp (no power signal).
My amp is
For préamp 2 X 6n3 tube
For amp 4 X EL84 tube
Where can i take the signal (on the two 6N3 ?), must a put some resistor to have the good impedance ?
I would like to make
CD player---->preamp (amp modified)------>another power amplifier or mixer...
Sorry for my english
Can you post the existent schematic?
Re: Make a preamp with an already buil amplifier
It doesn't sound like this design has a dedicated pre-amp stage from your limited description. I assume the signal goes straight from the volume control right into the first stage of the power amplifier. The 2 6N3 are part of the driver circuitry of your amplifier - EL84 is a single power pentode unlike say the ECL86 which is a triode/pentode. You'd be better off building a little line stage for this application - a good diy first project IMHO.. :D
