Finished off my latest LokSound conversion today. A Select Direct decoder with a sugar cube speaker in a Proto 2000 RDG GP30, this is the newer version GP30.
Fairly straight forward install, the decoder fits into the space provided with the OEM light board which was completely removed, the speaker fit between the decoder and the housing for the speaker on the sound version.
All connections were hard-wired to the Select Direct.
The newer version GP30 has all LED’s including lit number boards. These were hard-wired to the aux function buttons and programmed via the LokProgrammer.
