Repurposing a PS Audio Superlink II

Hello All,

I have an old PS Audio Superlink II I am considering to repurpose as a preamp chassis for a DIY FrontEnd 2022. The existing circuit board takes up the entire chassis, so I will remove that. It has four capacitive touch sensors that I would like to retain, since I plan on using relay input-switching. I have been looking for ready-made circuit cards to interface with these switches, but the only ones I found are from adafruit https://www.adafruit.com/product/1375. I would be interested to lean if there any other possibilities. I do not have the equipment to work with SM components.

Thanks for any help!
