L1 is used to adjust the frequency of the 9.00 MHz crystal. T1 is a 455
kHz tuned circuit. You can probably make a new one from an old 455 kHz
IF transformer. Q1 and Q2 are type MPS-3693. I'm sure that you can find
them or an acceptable substitute. Unfortunately, the values or part
numbers of L1 and T1 are not given. I'm sure that Ten-Tec can help you
I have the data sheet for the FM board. I can scan it for you. It shows
how to interconnect the board and provides a circuit description and
