Gp9 upgrades?

Probably not.  By 1999 this should have been modular.  Do you have any other GP that sound better?  Could be a speaker or maybe a faulty component.   G

I was thinking maybe like an upgrade to railsounds 5.0 or something along those lines.  Currently it has 4 rpm levels- 8 would be nice.  The sounds also are "crackly" and it seems you can hear them "looping".  Maybe upgrade to legacy kit?   wouldn't mind trying a new fat boy speaker though.  Any recommendations where to purchase?

For Lionel upgrades check out electric railroad.  They just upgraded the railsounds boards to rs 5. Www.electricrr.com

       
       


I checked out the link but it doesn't really say anything specific about the sounds other than there is a kit.  Has anyone used tthe before?

There is no legacy kits.  They are TMCC/RS kits.  You can search Lionel's Parts sight and look for a later RS 4.0 set.  I think you need to contact Lionel to get RS5.0 and you may have to turn one in to get one.  ERR did upgrade the sound sets.  G

       
       


Well I talked to Electric railroad and Ken couldn't tell me much about the kit sounds nor could he let me listen to them.  I aksed how many rpm levels there were and he had no idea.  I would think the company would have a link or video to let customers listen to the power before they purchase.  In addition I called Lionel customer service hoping to get some info on railsounds 5.0 and that got me no where as she had no idea what I was talking about and didn't seem to want to help anyway.

Also the sound level are different on some sound sets when used on AC motors versus DC motors. Don't ask why.
