Recently  received repaired 588AT S/N 10C10977, repair #R-8329.  Everything 
works fine now, but would appreciate some explanation of how repacing a 
defective 455 filter would restore the antenna tuner to correct operation.
 
My only symptoms were failure of the ATU to function, don't notice any 
diagnostics related to the ATU.  I'm concerned that the ATU is intermittent.

Dear Curt:

The filter is in the low level transmitter chain. The filter was intermittent 
causing the transmit [power to drop below the threshold needed to activate the 
tuner.
