Fitting sound to Farish Class 37 & 47
« on: January 09, 2018, 10:16:00 am »
Hi all

I am thinking of adding sound to my Farish Class 37 & 47 both are of the newer design with built in 6 pin sockets on a PCB that runs almost the full length of the chassis

All the online guides I have seen involves removal of the PCB and hard wiring the decoder in place and the machining the chassis were the fuel tank is to take the speaker,

Is all that work necessary,  would it not be possible to use the Zimo 6 pin decoder and leave the PCB in place and just make the room for the speaker.

Don't want to order the 6 pin and then be lumbered with it because it didn't fit being longer than a standard 6 pin decoder, then have to shell our for the wired one as well.

Anyone successfully added sound using the Zimo 6 pin decoders.

Thanks

Paul

I've got a Zimo 6 pin (on wires) sound decoder in a Farish 47 with the speaker in one of the cabs (I had to remove the cab interior) so it is definitely possible.

If you get the version with the 6 pins on wires and you decide the decoder won't fit with the PCB in then you can always cut the wires to remove the NEM 6 pin plug and hardwire it.

Cheers, Mike

I removed the PCB when I fitted a LokSOund Micro v4 to a farish class 37:
Some pictures.

If you decide to use the blue wire for the common lighting connection rather than one of the track feeds (as per standard 6 pin installation) then you'll need to increase the resistor for each LED. I didn't and now my class 37 no longer has the high-intensity head-lamp.


With the extra functions that most sound decoders have you can also have independent control over the tail-lamps. I have independent control of them so can have them switched on at both ends when parked, just the rear ones or have them turned off when pulling at train.
