The original design calls for tap washers used in sinks for the cores. This was done by Ashhar Farhan VU2ESE the designer of the BITX so Indian hams could get the parts easier. I had these cores in my parts so I decided to use these instead.

BITX Bandpass Inductors
LI, L2 & L3 wound for 2uH for the BITX band pass on 20 meters. 24 turns of 28 awg magnet wire over off brand T37-6 cores. The G4COE inductance chart calls for 26 turns. Using my meter came out to 24 turns. This may be due to the EBAY cores. Hot glue will hold the wraps on the cores.
