Commodore 64 and 128 (C64 / C128) RF Modulator Replacement
Commodore 64 and 128 (C64 / C128) RF Modulator Replacement!
Based on Texas Instruments THS7316 HDTV amplifier chip.
The board has a solder jumper. Leave it open for “short board” C64s that use 5V VIC-II-chip. Solder the bridge if you have a “long board” that uses 12V VIC-II. C128 has 5V VIC-II chip so solder jumper should be left open.
Long boards = Assy 250407, 250425, 250466
Short board = Assy 250469
Note ASSY #326298 is not compatible with RF modulator replacements.
GND1 should be connected to ground on long boards.
For short boards it’s not needed as the ground is available on RF Modulator pin 3.
