As is commonly known ZTC control units can be switched to run locos fitted with Zero 1 decoders, which for me is a very useful facility. However,in that position my 511 will now produce only around 14volts, insufficient to drive my locos with Zero 1 'chips' although it's fine for locos fitted with other decoders. I know I can change the voltage for the latters' use but is there any way of altering the voltage output for Zero 1? This may be a fault but now that SBX models has relinquished the contract to supply and repair ZTC items, there seems nowhere to go for repairs or replacements. I note that ZTC have booked a stand at the forthcoming NEC show and it will be interesting to find out why. I don't suppose anyone has a circuit diagram of the 511 to spare?

I'm not at all familiar with the ZTC controllers so can't answer any of you questions
If you do find out anything from the NEC show then please post it here so that the rest of the world is kept in the picture.
Best of luck with your queries.
