My trusty U87 has been giving me a little trouble lately, I am getting random pops every now and then, that can sometimes ruin a otherwise perfect take. The capsule has been overhauled by Mr. Thiersch a little more that a year ago and I'd like to give the electronics a general overhaul.
I haven't seen a lot of talk here about U87 electronics, but I'd like to dive into this a little. As my mic has the battery option I believe this schematic would apply: U87schematic
For a start I think it wouldn't hurt to replace all existing electrolytics and tantalum caps as they all original 1979. As I'm not using batteries with it, there would be lots of space in the mic to use larger film/foil capacitors, which is one part I'd like to do some experiments on. If anyone has specific suggestions as to what one may try out with this mic I'd be very interested to hear about them.
Thanks, Marten
