Now that's a thing of beauty!
Interesting little double cross-over at the top. What amp are you using?
I would have predicted S-ATT = 18dB with a 10dB attenuator, however 14dB is within the range that others have reported (8000's seem to vary a little bit in terms of their internal construction, nobody has a handle on this yet, even after asking Apache directly).
Two pages of thrash all because of an assembly error at the factory. You had everything correct from the start! At least now we'll know the symptoms if someone else asks about the same symptoms.
So how's your transmit IMD? I bet it looks very nice, now!
73!

Re: Got the RED & YELLOW
The amplifier is a former Alpha 78.
However the 8874's were replaced with a pair of Eimac 3CX 800's....
I released a pair of 9500's when the issue of repair/replace come to the forefront...
But the modded 78 served me well has the spot auto tuning.. runs cool at 1500 has plenty of head room....so...
