Reply to "Converting MTH 2-rail GP-40 to DCC - specifically the bulbs"

I was certainly thinking that if I blew the bulbs, my plan B would be to replace them with LEDs instead. I guess I should take a look inside and see how hard that would be to do as a plan A. 6V is an odd number compared to other stuff I've done (in HO and N mostly) and probably isn't worth the hassle to me of working out what the proper resistor value should be. I'd be so nervous I'd got the values wrong.

As I'm based in the UK, it's not that easy for me to sell the ProtoSound 2.0 board. I certainly couldn't be confident enough in it to put it up for sale on eBay - the grief of returns/refunds to the purchaser across the Atlantic wouldn't be worth it if it turned out not to work. I'll have to think about it.

Thanks for the advice. I'll let you know how I get on - I have an HO scale layout to finish first which is due to be exhibited in like six weeks, so that's on a deadline.

Regards, Bevis.
