Does anyone have a source for parts so i can assemble my own barrel jack adapters? They are the things that the MYH power bricks plug into to use with the TIU’s.
What is the size of the hole in the plug? It may be metric.
The MTH transformers and accessories use a 5.5/2.1mm jack and plug, they're very common and can be had everywhere. Hundreds of listings on eBay for any combination you can imagine.
The Lionel plugs used for command bases are 5.5/2.5mm jacks & plugs, they're less common.
I bought mine thru Amazon. They have straight and 90 degree banana plugs you just solder onto your power wires.
