FT-101B: AF Unit BOM

Bill of materials for the Audio Frequency (AF) unit of the Yaesu FT-101B

This is a series of articles about my Yaesu FT-101B

For this I used the serviceimanual available at Fox Tango International My unit is from May 1974. I’ve used these lists restoring it. I hope it will be useful for someone else; it was helpful to me.

In each case I include the image I used for OCR, in case there are errors. If you find any error or omission, I would appreciate it if you let me know at lu2dfm-gmail.com.

Note: this information was obtained from public documentation; any errors or omissions are unintentional. Please verify any data you obtain here and use it at your own risk.
