Marantz SM 500 DC panel lamps

Does anybody know a source for the soldered in axial lamps that Marantz used on this product. I
found a source in Europe but I would prefer a domestic source. The lamps themselves are a
axial config. with leads that get soldered to a longitudinal bus that runs along the top of the
front panel with solder points for each of 6 lamps. They appear to be a low wattage design.
