guys, thanks so much for your valuable feedback. Also sorry for the confusion I caused with the 6.8k resistors, in my most recent schematic I changed them to 2.2k. As some of you pointed out this is more common and also used in the KM84/U87 circuit, it shouldn't really change the circuit is working much, from what I gather.
Anyway, I still have three problems:
1. part count is still pretty high (space!)
2. the little NTE10-3 tranny lacks shielding, so I'm not sure how reasonable it is to go forward with it (the mic itself has a plastic housing)
- I would probably need to implement a permanent pad, otherwise I might overload the little transformer. What do you think?
