HK 400XM Need Service Manual


2007-11-29 3:21 am
Just got one such beauty through ebay. I'm eager to test it versus my Naks RX505 and 680ZX, want to measure frequency response and I am curious if indeed the upper bound is 24 KHz +/- 3dB as advertised. I need a service manual - could somebody send me a service manual ?

Thanks in advance
