MRF454 RF Power Transistor – Motorola-Style 60W HF / CB Linear Amp Final – New old Stock
$49.00
MRF454 RF power transistor for HF, CB, 10-meter, and radio amplifier repair projects. This part is commonly associated with older CB linear amplifiers, HF RF amplifier stages, and vintage radio repair work where original-style RF output devices are becoming harder to find.
This is a good RF Boneyard bench-stock part for technicians, builders, collectors, and radio repair users who need a possible replacement, matching candidate, or donor component for older RF power amplifier sections.
Old RF parts like the MRF455 are getting harder to source in trusted condition, making this useful for repair benches, restoration drawers, and “keep the old rigs alive” projects.
