So you are not getting the advertised track voltage either. I spoke to Gaugemaster again and the very helpful chap indicated that there have been supply issues with the power supplies but the Prodigy Advance would still work. However, I am not convinced the new generation of decoders from some manufacturers are operating to design due to the lower voltage supplied by some DCC systems, primarily in controlling built in keep-alives and speed performance (yes I know we don't all operate TGVs 😁) and I would like to know if the this is actually true and wanted the higher track voltage to rule out any loco/decoder issues? Anyhow, the retailer was happy to give a refund and I am now considering either a Z21 or an ESU ECoS.
