    Default MTM5500

    My MTM5500 has the following problem:
    The power amplifier transistor burnt-out.
    Could anyone tell me what the model of this transistor is so I can do the repair?

    Grateful

    there are schematics in detailed service manual for this model, but one needs to be an expert to understand them

    133/5000





    I decided to open the radio and check, I am suspicious of a transistor model RD35HUF2, it follows its specification second datasheet:

    DESCRIPTION

    RD35HUF2 is MOS FET type transistor specifically

    designed for VHF/UHF RF power amplifiers applications.

    APAPLICATION

    For output stage of high power amplifiers in VHF/UHF

    band mobile radio sets.

    If anyone could confirm it would be fine!

    If anyone has the circuit schematic and can share it I will be very grateful.
