hello there
i have just finished construction of an se kt88 stereo amplifier based on mikeal abdellas design.

however upon firing it up i noticed i am not getting any gain.
with a dual channel scope viewing the input and out output it can be seen theat the output is lower than the input (input just under 3v pk-pk and output just over 1v pk-pk)

all voltages throughout the amp seem fine

if any one who has build this amp has any ideas please let me know.

cheers
