I think I remember there's been a thread about a V77 that suffered from hum, but I can't find anything with the search function. Now my V77 suffers from a little hum. What can it be, the caps inside the mic, or in the PSU?
Ah! please continue your lifestyle Harv and you will get very old.
The V77 problem: I unscrewed the housing, looked for loose screws or anything, found nothing. After putting it together and I mean fermly, the hum was gone completely.
Thanks again Harv, you've really helped me (another old fart)
