First off how's everyone doing? This is my first post btw . . . and I have no clue how to trace wiring diagrams. I know all of the symbols, I just get confused trying to trace things around.
Ok, so here's my situation: I have this really nice Russian made microphone from the company Oktava. It's an MK-219. I have been reading posts about what can be done to open up the mic even more, improve transient response and so on. I've completed all of the physical modifications, but what's left are the electronics.
So I have the schematic in hand and took a photo of the board to try and make some sense out of this . . . and now I'm scratching my head trying to find R1, R2, C2 and C3. There is nothing written on the board to even give me a chance to begin this easter egg hunt. I've drawn it out by hand to get more familiar with the board, but I'm getting no where. Obviously schematics were not designed to mirror the physical board that I'm staring at.
I read that it's "standard practice" for schematics to be written from left to right. Maybe that explains why R1 and C1 increase in number as you look from the left to the right? If so, then is R1 the first resistor the Condensor/Capacitor output wire connects too?
Anyway it calls for replacing R1, R2, C1, C2 and the FET (which I found because it looks nothing like any of the other components).
I uploaded a photo I just took of the board, and also provided the schematic. Is it possible for someone to tell me where these components are located with the information I provided? If anyone has the time, and doesn't mind giving me a hand, I would hugely appreciate it. Also, I ordered the upgraded parts online and then getting my friend to solder them for me.
Here are the P/N's if anyone was curious . . .
FET REPLACEMENT P/N TOSHIBA 2SK170BL
C2 REPLACEMENT P/N P4860-ND (COG Monolith Cap)
C3 REPLACEMENT P/N P2019-ND (Tantalum Cap)
R1,R2 REPLACEMENT P/N MOX200J-1000ME-ND (1G MOX Thick Film Resistor)
So if anyone can at least answer some of my questions and more so tell me where these 4 components are located, that would be sweet. Thanks!
