Hi Duncan, if I recall correctly I posted photos of my original router absorber mods in this tweak thread. P20 & P15 Regenerator Performance Tweaks and Digital Stream Enhancements, plus BHK Preamp
But yes I only installed directly on chips. Avoiding capacitors or step up transformers. The absorber changes capacitor inductance so I avoid getting close. Ionly use absorber on lids above toroidal transformers My Docsis3.1 Netgear Nighthawk A6 Modem router switch arrived today Unfortunately Spectrum my ISP has to hard code a connection. So it is entered on a programmer ticket. So tonight still running off A cellphone wifi hotspot. I can say it doesn’t compete SQ wise with the wired and tweaked ethernet of the previous Nighthawk . I am getting glare and digital edge the Mac M-1 Mini wifi is not up to the task. It is a whole different animal with audiophile ethernet cords by inakustik. I have lost a bunch of 3D space around images with eifi.
I hope I can get the modem running in a couple days before my Daughter leaves and new router absorber install s performed. I have got a whisper elite doing router switch lps power cord duties.
