I would like to know if anyone can tell me if the LA-2A is known for rolling off the high-endabove 5K in frequency. I built one exactly as it was originally made and it works very good except for the high-enddrop off. Is this normal for this model by Tektronics. Thanks for any help you can provide.

All compressors with kill the high end to some degree or another. The LA2A is no different. How much and at what freqs are affected depends on all the things related to using compression. The program material going into the compressor, the compressor attack, release, threshold, ratio and the gain reduction it does. On the LA2A you only get manual control for level (which controls both level and threshold) and for gain reduction which is pretty much ratio but is related to the level control as well as attack and release which are fixed, but vary in settings dependant on the input level and program material content.
