Quadra 660av speaker ticking

[jdlanza]

I’m working on a Quadra 660av that boots from the CD-ROM, but does not chime at startup.  After boot, the speaker makes a tick, tick, tick noise which speeds up and slows down seemingly at random.  Any thoughts?

The ticking may or may not have anything to do with the problems I’m having getting the SCSI2SD drives to initialize.  It’s version 5.1 and been set up using the same setup file I have been using for my 6100s.   Is there something funky with the SCSI bus on the AVs?

thanks!

Has it been recapped? Sound issues such as those could be bad sound filter caps.
