Hi,

i am new to this forum.

please let me know has anyone tried to repair DNM amplifier 455E, from dnmaudio. i have two of them and have the same problem. no sound.

the relay do not operate. there is output on each channel but the sub output was in flapping before the entire unit was shut for no sound.

please assist, these are very good power amps as far as 20 watts each channel and 80 watts output for sub is concerned.

regards,
Hemant.
