The RGB Tuner is a device used during CRT RGB modifications to optimize the RGB output signal. It eliminates the need to manually test various resistor values or build custom blanking divider circuits. It is particularly useful for chroma chips that require precise cutoff adjustments or those that blank at non-standard voltages (e.g., 2.5V).

The JVC AV-32D202 (D-Series, AC chassis) supports analog RGB through the micom's OSD video signals. This modification allows the injection of external RGB signals by tapping between the OSD output and the Y/C Jungle's input. The mod utilizes the OSD circuit for RGB, Component Luma for sync, and SCART pin 16 for blanking.

The Sony KV-20S42 (BA-4D chassis) is a composite-only 20-inch Trinitron CRT that can be modified to support RGB and component input. The mod utilizes a mux method to inject RGB signals. This modification is also applicable to the following Sony models: KV-13M42, KV-20M40, KV-20M42, KV-20S42, and KV-20S43.

The Samsung TXH1973 (19", 4:3 CRT) is RGB moddable. This modification process is also applicable to the following Samsung CRT models: TXH1370, TXH1372, TXH1373, TXH1386, TXH1970, TXH1972, and TXH1986.

The Sony PVM 8041Q is a professional monitor capable of displaying PAL, SECAM, and NTSC signals. It utilizes a 250 TV Lines tube (rather than the 450 TV Lines Super Fine Pitch tube). Note that while basic controls are available on the front panel, most geometry and color adjustments must be performed manually via internal controls inside the unit.

The RGB mux mod for the Hitachi 36UX01S (Chassis: M10LXU) allows for more vibrant colors and sharper edges compared to the built-in component input. This modification targets the Toshiba TA1310N jungle chip. It is also applicable to the Hitachi 32UX01S and other sets utilizing the TA1310N datasheet. The mod involves injecting RGB signals into the Picture-in-Picture (PiP) circuitry, which supports standard 0.5Vpp analog signal input, rather than the OSD inputs which require 1.25Vpp and may result in a dull image.

The Panasonic Roadshow is a compact VCR/CRT combo unit suitable for retro gaming and VHS playback. It features a unique function for audio transmission via FM. Known variants include the PV-C921B (Black) and PV-C931W (White).

A Load Lamp is used to safely test electronic devices by limiting the current, preventing potential damage during the testing process.

RGB modding involves intercepting the signal path between the OSD (On Screen Display) chip and the Chroma/Jungle chip (the main video processor). The OSD chip generates menus and overlays, which are muxed (mixed) with the video input signal within the chroma chip. For a CRT to be RGB moddable, these typically need to be separate chips; newer CRTs that integrate these into a single chip may not be moddable.

The Sony Trinitron KV-F29MF1 is a 29" multisystem CRT television built on the G3F chassis. It is capable of being modified to support RGB input. Key technical specifications for this model include the CXP80424A-081S OSD chip.

The Sony GV-D800 is a portable digital video cassette recorder featuring a 4" color LCD screen. It is capable of playing back Digital8, Hi8, and Video8 tapes, but it can only record in the Digital 8 format.
