Hey fellas,
Ok, i have a rode K2, it has a NOS mullard tube in it. Same complaint as always, a little gritty on the top. I am interested to know if anyone knows of a DIY electronics upgrade for the mic and power supply? I have searched the net high and low, including slutz, and all that comes up is the tube thing. There is one guy who does an electronics mod, his name is John Bonnell, he has great reviews, if i come up empty on the diy thing, I will use him on the K2 for sure. I've been getting into doing mods myself lately, it's a great way to get a lot of bang for your $. I am not great at understanding electronics design, but i'm real good with an iron, and following directions

and doing swap component upgrades.
any direction would be appreciated
thanx
