skilled person could replace the caps with polystyrene, and
replace the electrolytic caps as there's plenty of room.
I seriously doubt replacing this cap with a styrene would change
anything to teh sound.
The voltage across it is extremely low and CoG are very linear.
BTW, Sw2 is the High pass filter.
For quick reference I opened up my Takstar CM60 to see the
comparison.?The CM60 is different in the following ways:
CM60 lacks the common mode choke and ferrite beads but adds caps
from pin2/3 to ground
CM60 has holes drilled under the capsule bias resistor and
output capacitor.
CM60 is lacking the trimmer pot but has a location to put one.
Through hole caps on the low pass circuit.
No inductor on the boost positive rail.
Given the choice, I'd say get the CM63. The capsule internals
are identical, but the CM63 capsule housing is 3mm shorter,
putting the diaphragm that much closer to the front.
It would be an interesting experiment to put an identical
circuit in each and find the difference in response with the
different venting and different grill pattern.
I will say that if you're looking for a 22mm mic body and don't
need the PAD and High pass, get the CM60 over any MXL SDC. It's
only a few mm shorter and the body is much higher quality.
I think I'm getting better at this. I was going to trace the PCB
but it would have been more work.
Next I might do an old AKG Perception 150 I got. It has one of
the longest 22mm SDC bodies at 160mm and wide vents. I took a
quick peek at the PCB and it's almost identical layout, cone,
and components as the Takstar CM63, leading me to believe it was
manufactured by the same people.
