This is an original RF modulator module for the Sega Master System — not a reproduction or aftermarket replacement.
The RF module is responsible for converting the console’s video and audio signals into an RF output for use with televisions via the antenna/coax input. Failures in this module can result in no picture, heavy static, weak signal, or distorted audio when using RF output.
Ideal for fixing:
-
No RF video or audio output
-
Excessive static or unstable RF signal
-
Physical damage to the RF module housing
-
Broken or corroded RF output connection
All modules are used, tested, and cleaned, and are fully functional at time of testing. Using an original module ensures proper electrical characteristics, correct PCB fitment, and compatibility with the console’s original RF circuitry.
Condition Notes
-
Used original part; cosmetic wear may be present
-
Shielding and connector intact unless otherwise stated
-
Designed to solder directly to the Master System PCB
⚠️ Installation requires desoldering and soldering and is recommended for users with intermediate console repair experience.
