Open, through-hole RF-modulator replacement with adjustable C64 luma and chroma output levels.

The repository supplies KiCad sources, Gerbers, a schematic, a BOM, and assembly and adjustment instructions. Components were estimated at about $12 when documented, excluding PCBs and shipping. Building the board requires through-hole assembly; installing it requires safely desoldering the original RF can and selecting the correct jumper configuration. Using the shortboard setting on a longboard can feed the wrong voltage and damage the VIC-II.

Replaces the C64 RF modulator with composite, optional S-Video, and mono or dual-SID audio connections.

The official store listed RFOUT! at 22 EUR but out of stock on 2026-07-30. It provides a composite socket, a 3.5 mm audio jack, and solder points for an optional S-Video connector; stereo output requires a dual-SID source and the SJ1 setting. Installation requires desoldering the original modulator. Measure the motherboard supply before installation: boards carrying 12 VDC or 9 VAC on pin 1 require that pin to be removed and a separate 5 VDC connection supplied to RFOUT!. Confirm the footprint, voltage, extension-board fit, and case height before soldering.

Replaces the C64 RF-modulator circuitry while retaining composite and S-Video through the computer's A/V port.

The current maker page remains online but exposes no price, stock state, or order control. Human inspection recovered a maker compatibility list naming PAL and NTSC Assy 250407 C64 boards and all C128 board revisions; Tavily did not render those list values. A 2020 independent review also tested a SixtyClone Assy 250466, where both composite and S-Video worked. Removing the original modulator and installing Shuriken requires desoldering and soldering. RF output is removed.

Discontinued C64C RF-modulator replacement with rear-panel S-Video and 3.5 mm audio jacks.

The original maker site is gone, and a 2020 discussion describes the closed design as dead. An independent review tested an older version on an Assy 250469 Rev. 4 C64C: the first board was faulty, the replacement worked, CRT S-Video improved slightly, flat-panel results were worse, and composite output was unusable in that setup. A later eBay version once claimed C64C and C128D support plus an AEC fix, but no surviving manual or seller page establishes its exact differences or safe C128 installation. Buy used only with a return option and exact revision documentation.
