Vic- It isn't a train transformer but just a noraml plug pack, it has no control options or anything other than inputs and outputs. You're right about the resistors generating a lot of heat 48w at my count. the only way can see to get this working is with a huge series matrix
! I know how to calculate Ohms law but I wanted a seccond opinion to make sure I was accurate and on the right track!
Sumpter250- I have looked at these regualtors and will be asking at my local electronics shop but most of the cheap (to make my buy worthwhile) ones only go up to 1A current flow.
60103- Again, that probably costs more than the transformer and defeats the bargain!
Billk- Lol, I once bought a Commodore 128 for $15 at a school fete and sold it for $152.50 on eBay. That following weekend was an enjoyable trip to the train shop!
