Ensemble RX III Ensemble RX III Bill of Materials
Band: HF

This page provides a Bill of Materials (BOM) for the entire kit. There is one BOM for all of the "common" (non band-specific) items, followed by a band-specific BOM for each Band implemented in the kit.

When inventorying, note that Tony usually provides one or two spares of each of the SMT capacitors (experience over 20,000 kits has proven these to have a high probability of at least one specimen being "launched" into the nether regions, never to be seen again).

If it is your practice to separate the SMT capacitors from their carrier strips when inventorying them, it would be wise to mark the ones from the black-striped carrier using a magic marker. This way you avoid possibly mixing the different-valued SMT caps up.

Also note that the kit comes with a single hank of magnetic wire made up of a 30 foot long length of wire. This is more than enough to cover the coil/transformer requirements, with some to spare.

DX Shipments Are in 2 Mailings

Finally, 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.
