This is a sampling of some of various console modifications I’ve performed. They’re all documented thoroughly elsewhere so I won’t go into details here, but the photos might be helpful for your reference.

RGB Modification
This Duo had severe ghosting after installing an RGB mod board. The culprit ended up being the induction coils on the RGB lines – replacing them with straight links cleared things right up. Shout out to Leon Kiriliuk (https://twitter.com/leonkiriliuk) for that solution.

This is the first time I mounted the RGB mod board on the underside of the main PCB and I like it-it’s definitely a cleaner run than running the preamp RGB+sync lines from the Hudson custom up to a topside-mounted mod board.
