hi new to group any help with mic fix a build choice SE2200t tube mic and uses a ecc83 Harma is lowest noise a nos Mazda silver plate noisy crackles and pop. Also tried a miniature valve with adapter sock but noises. Not sure if increasing biase resistor or change in heater voltage could help or adding grid stop may fix later noise issues. Also have spare capsules, triodes and pentodes and ability to make own pcb looking for nice low noise and retro mic build eyes on Gefell UM75 or C12 any advice would be greatly appreciated. Cheers
