John, Protosound 3 upgrade kits are available from MTH. A lot has to be changed out besides the boards. That includes, electro-couplers, leds, speaker, wiring harness. The kits come with everything and detailed instructions. I have done them for my own engine. Last I checked they are $199, with a discount if you join the MTH Club.

Is a plug in protosound system able to get a protosound 2 or 3 board? I have a RK-2501 Pennsylvaina Tuscan Red 5-Stripe GG-1 Unit that appears new in box. Any hope it can get off the conventional road so to speak? Thanks in Advance John
John, I post my for sale items right here on the For Sale or Trade section of this Forum. You have a better chance of getting an honest buyer. While OGR has no responsibilities for sales going bad, I have always dealt with first class people here.
Yes to upgrade, but that is a very basic early GG-1 with big bulbs and hardly any features. They also had a mechanical coupler integrated into the truck and in some cases not changeable with a proto coupler. It was like a Post War Design. For the cost your probably better off getting a newer RK model with PS-2 3V. Or splurge on a RK PS-3. G
I have done two or three of these. One was the gold version, some have sentimental value and folks do for that reason. It just has real limitations as a PS upgrade compared to the later RK versions MTH made. G
