    REMOVE your FT-736R TOP COVER, you should SEE battery (photo below) on Control Board.
    Instructions in the FT-736R Service Manual,
    Drop Down the Front Panel to access the Control Board.

    The Yaesu FT-736R VHF/UHF transceiver used a Sony battery,
    BUT it is mounted vertically (solder tab mount) on the Front Panel/Display Board.

    Panasonic CR-2032/VCN (Digi-Key P660-ND) 17,178 in stock at $1.17 each.

    The Yaesu part number BQ041-22803 for the bulbs (incandescent lamps), was discontinued long ago. I DO NOT recommend LEDs, since the FT-736R uses “light pipe” plastic.

    The Yaesu 757GXII Owners Manual specifies that Yaesu part as an 8V 100 mA lamp fuse.
    While any low current, grain of wheat type lamp, from 6 to 8 volts, is a suitable replacement,
    its current rating must not exceed 100 mA.

    Bill Patton, WY3A (West Chester, PA) sells a suitable replacement lamp (6.5V, 68mA “grain of wheat” bulb) that are right size (T1) for Yaesu part #: BQ041-228038V 100 mA Lamp Fuse Bulb.
    Two (2) Bulbs for $8.25 Post Paid, while supplies last.

    Cliff -
    Despite multiple postings (my QRZ page) about NO Private Questions, I still receive these Tech Help Questions. Illiteracy is a growing problem (now estimated as 15% of American population).
    QRZ Tech Trolls (never Answer question, Self Promotion) scare many Beginners that Need Help from publicly posting QRZ Questions.
    ==
    I publicly Post their Question in the proper QRZ Tech Forum.
    I accidentally left out the Bulbs in Title, for this question ... and QRZ 30 minute Edit Window closed.
