Hi all, I have a 5000A with F1040-1s that I just completed skippy124's mod on. The final step is to adjust the bias current. That is where I've run into trouble, I'm following the service manuals procedure of connecting 10 ohm 1 watt resistors to each speaker terminal, removing the quick acting fuses and measuring DC milliamps at the fuse holders. The problem is I'm onny measuring 0.86mA no matter how I adjust the bias pots, I thought perhaps the pots were dead, but removed one and it tests fine. What am I doing wrong? Any help would be greatly appreciated.
