finishing up my MK7 (finally) just did some measurements on the heater .
i can only get it up to 6,35 V with the mic attached .
i use EF 86 , PSU PCB after max (ioaudo) schematic .
mic works , but got a little hum .
also the back of my mic sounds quite different to the front . i use a Dale M7 with thiersch mount.
i know this project was done some time ago , i did a search and couldn´t find anything , also no troubleshooting thread .
Can anyone chime in who finished this mic how to adjust the heater voltage and maybe get rid of the hum ?
thanks
