I used Milcom PAs in the 90s in both their VHF and UHF versions. I was  never 
able to get any schematic information from them but they were very  generous 
about repairing their units which
seemed to crash regularly. They modified the designs regularly and finally  
added heat sinking
wings to the RF devices on the strips. Your unit is a 250 watt PA designed  
for a maximum of
15 watts in and it was designed to operate in the 144-152 Mhz range. It  may, 
or may not, have
a driver board PN 240-096. I have the 160 watt versions, both with two  
240-094 strips and both
units described as 40 watt input units. But one has a driver board for the  
strips and the other
doesn't. Go figure.
 

Milcom International was subsequently bought by Powerwave Technologies and  
finally was
absorbed by Crescend Technology. Tessco is one of their distributors.
 

I sent one of the Milcom PAs to Crescend for repair and they replaced the  
Milcom 290-094 strips
with, guess what, Crescend 290-094 strips. They're identical. So, if you  
need new strips, they
have them although I don't know if they will supply them as parts without  
any service.  Between
parts, labor and shipping it ended up costing over $400. A new replacement  
would run about
$1200 but it does come with an impressive 3 year warranty. Warranty on  
repairs is the
typical dismal 90 days.
 
All of which is a long way of saying, no, I don't think they did much in  the 
way of service
manual support. There were some very nice people there but one of the  movers 
and
shakers (Tom Litty) died unexpectedly of a heart attack and the company  
never seemedd
to recover.
 
Hope some of this may give you some insight into whether or not you are  
throwing good
money after bad.
