In particular for the purposes of this question. The Tsunami TSU-1000 type DCC/sound decoders. I know they warn you not to remove the shrink wrapping around the decoder, but is it only there to hold the heat sink along the bottom of the decoder and would it's partial removal over the the wiring sockets at each end cause any harm to the decoder from overheating. I would like to remove those sockets and solder the wires directly to the board in order to reduce it's thickness.
