Bill of Materials Introduction


DX Shipments Are in 2 Mailings

If you are a non-US builder, please note that Ensemble kit shipments to DX locations are done in two mailings:

  1. The first mailing includes the circuit board, ICs and capacitors.
  2. The second mailing includes the resistors, connectors, cores/wire, and hardware.
