[BC] Marti HRC-10A replacement

[engineermike]

Hey folks,
  It appears my old HRC-10A STL combiner has finally bit the dust or 
almost anyway.  Everything looks good on the STL's but on the receive 
end my left channel is about 10% pwr while the right channel is 110%.  I 
tried swapping the cables from the splitter and checking several other 
things such as attenuation on the receivers and everything looks good so 
the only thing left that I can imagine is this combiner.  At the moment 
I don't have any of the proper test equipment to confirm this.  So with 
that said what do you guys use in a case like this.  Two mono STL units 
that are a back up to our digital link.  I do have a call in to BE to 
see what Marti now suggests and their cost.
Thanks in advance
Mike
