OT: Probs with OB-8 (Already!)

[Gavin Muir]

Hi all,

	I'm having a minor problem with my new (to me!) OB-8. It's a mint rev B5,
and unfortunately I do not have the service manual (nor can I read the
incomplete online version). 

	I managed to fix one problem (a couple of keys which triggered poorly; the
bus cable was coming unseated on the bottom of the keyboard), but the other
is a little more technical. It seems that voices 5 through 8 seem somewhat
quieter than 1 through 4, and as far as I can tell, this is a fairly recent
development. I'm assuming maybe the Obie needed to settle a bit after
travelling nearly 5000 miles in a box?

	Anyways, any input is appreciated on how to fix the problem, and whether
or not this is a sign of something worse on the horizon.

Cheers,
Gavin.

P.S. Other than this little episode, I am WILDLY happy with my OB!
