Looking at the original board from my Kato n scale FEF and the original from my sd40-2 mid it appears that the 58741 can work in the FEF. Has anyone done this install?

there apparently are solder pads for adding capacitors, can some one tell me which side of the cap/choke gets soldered to which pad??? this part of it befuddles me :-(

The FEF3 has been done by myself and a couple of others so far.


Hope this helps!

That sure makes a sound install easier Kelley!
Did you ever figure out the motor control CV values to get the loco with that coreless motor to crawl, and to smoothly run at all speeds?  You gave me the ESU V4 sound file for my FEF back when I had problems getting the LokSound V4 to smoothly control the motor, but it is still not what I would consider smooth.  ESU are wonderful decoders, but they have heck of a time controlling that coreless motor.
