Once upon a time, in a galaxy far far away...... I was saving lots of tubes and modifying them for RGB to sell and ordered a bunch of Sunthar's RGB Mux boards and components. I have so many I will never use them all. In an effort to pair down and offer something that is currently unavailable, I want to sell the remaining spares I have left.
If you are unfamiliar with these, they offer a clean, easy way to modify your tube for RGB.


The kit includes the following:
-RGB Mux board with most components pre-soldered (2x 1k resistors, 3x 75ohm resistors, 1x diode, 10pin quick connect, SCART female)
-2ft pre-crimped rainbow ribbon cable
-Remaining items that need to be soldered: 3x Diodes, 3x 470 Ohm resistors, 4x 1k Ohm resistors (Each mod requires different values and configuration, but these cover 90% of sets)
-QR code on package with link to detailed instructions
I have the following number of units available to ship:
- Revision 1.2B -
2 units SOLD
- Mini Revision 1.2C -
20 units SOLD
1 kit: $25/per unit shipped CONUS
3+ kits: $20/per unit shipped CONUS
If you want them all I can make a private deal.
I ship same day, in a box with plenty of packing and close it up with security threaded WAT and print your label on a Zebra.
Payments accepted: Zelle, Venmo, Paypal, BTC, ETH, USDC.

- No need to spend time connecting all the grounds together
- Easier to solder the RGB in-line resistors, diodes and 75ohm resistors (this can get quiet messy)
- Ability to disconnect the back of the CRT TV when needed (10 pin IDC connector)
- Adds stability to the mod. No need for hot glue etc. to hold things in place
(Above numbered summary was pulled from Sunthar's site)
