still no juice! i put in a 100k resistor and its a touch better but not by much. At 1/4 volume on the preamp it sounds clear, but its still very very quiet. After 1/4 volume its nothing but distortion and you can't hear any of the music.

any suggestions?

and i am using a 1/2 watt resistor..... i have a 1/4 watt one if that would help.... again I don't have a clue about this stuff yet.
 
I made a stupid mistake with similar outcome on my first build, what you should do is take Voltage readings on everything (EVERYTHING) and let us know what the voltages are at certain points. I did this over and over until I realized that I was using a 6vCT heater winding when I thought I was using 12v
