General
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:
- The first mailing includes the circuit board, ICs and capacitors.
- The second mailing includes the resistors, connectors, cores/wire, and hardware. (go directly to build notes) (go directly to build notes)
