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 |

Output jacks shorted to chassis? Input jack shorted to chassis? Come back after a good night's rest and look very carefully for wiring errors.
Check for grounds where they don't belong and shorts with a dvm..
