    Power Amplifier for Guitar

    audioguru, could you explain what you mean by input impedance?  i`m a bit unclear about it.  sound as an ac wave enters the signal path (input of the amp) and from that point where is the other point(s) where you are measuring the resistance along the signal path to get the measurement of input...

    Power Amplifier for Guitar

    Hey folks.  Am hoping to get some tips and advice regarding the next stage of a guitar amp I`m working on with a lot of help so far from this forum.  Thanks very much! I`m getting set to build the power stage of the amplifier...the first stage is found from a schematic and design that audio guru...

    Solid state...transistor amp design problems

    audioguru asked "Yes, if the capacitors have correct values, have the correct polarity and the amplifier has an input impedance of  47k or more." well audioguru, here are the capacitors i`m using at present.  numbers are based on the schematic i supplied (found above)...sorry, i don`t have the...

    Solid state...transistor amp design problems

    so, if i`m to understand correctly -- this pre-amp could quite possibly be functional at this point?   hmmm...that would be great actually.  that means i can start working on the speaker driving portion. am i right in my understanding....that these voltages i posted as "measured" from the made...

    Solid state...transistor amp design problems

    still trying to work with the help from the forum.  another day of no progress...the amp still isn`t producing any sound.  any ideas what i can do from here?  i have put in the resistors on this drawing as audioguru suggested, measured the voltages and noted the readings....  scratching my head...

    Solid state...transistor amp design problems

    I`ve tried a few different things with this amp....changed the resistors a bit on the collectors and emitters....and biased the base and am getting a BE voltage of .75 seems like it should now work....at least some sound should be coming out right? but still nothing. any suggestions?

    Solid state...transistor amp design problems

    Hey folks.  This is my first posting in the forum.  I have been working on making my own solid state amp from scratch...having some problems i guess understanding some basic concepts.  in short, this is what i have built ....  it doesn`t seem to put out any sound.  I`m hoping someone will have...
