I just purchased an L5 and it came pretty messed up.  I have now just noticed that they replaced one of the original speakers with an 8 ohm speaker (so it has a 16 and an . 
When I turned it on, the compressor light briefly lights up and then goes out regardless if the comp switch is on or not.
The volume is very low.  To get any kind of sound out of it you have to turn both pre and pwr amp volumes up to 8 or so.
The compressor does not work or light (just that initial light).
The power LED does not light at all.

When I disconnect the 'replacement' speaker none of this changes. 

Getting ready to return it.  Any suggestions from you guys?  Did they fry it with the oddball speaker configuration?
 
and it had super gummy pots but I fixed that with electrical component cleaner.
