I'm no expert and not knowledgeable on the 89, but:  #1 You need to know 
a lot more about it!
If it's nearby and you can pick it up would it be possible to inspect it 
and test it at its location.  IE, just take a dummy load along and a 
small rig to drive it.  They aren't that difficult to hook up and key.

Untested and without tubes it's not worth a whole lot, although some one 
might pay a small fortune on e-bay.  Not me.
It could be the buy of the century, or it could be a waste of time.  No 
way of knowing without looking and testing.

IIRC the 89 is the manual tune version using a pair of 3CX800A7's.

No tubes?  If you have to purchase new ones. l think the 89 uses 
3CX800A7's, but I'm not sure. If so they are kinda pricey. Figure $600 
to $800 for tubes unless you have contacts.  Power supply.  Transformer 
is again about $800, give or take.  Maybe more.  I've seen them in good 
shape go for around $3 grand, sometimes substantially more and less.  If 
the cabinet is in good shape as well as the PS it might be worth a $1000 
if you are willing to do a lot of work and invest a fair amount of time.
