Sir; Hope I am doing this right, it is my first time. I am looking for a 3395.0 Kc crystal( part # L77-0123-05 ) for the carrier unit board (# X50-0009-00) of a TS520SE Kenwood Transceiver (Ser # 0020474). I talked to the people on the west coast and they tell me this part is not available any more. Is there another out let? Thank you G.A.Gutmann
