Hello,
My obsolete Agilent 8156A Optical Attenuator burned internal fuse the other day out of the blue, while in operation for 2 hrs and since then, keeps doing so. I am suspecting the problem is in the PS. Before I try to rev-eng / repair it, I just wondered if anyone has seen a 8156A service manual - I was not able to locate it anywhere.
Thanks, Jiri
