Hai Hi-Fi volume replacement module?


Hello. I have an Hai Hi-Fi first gen, not Hi-Fi 2.

I have six volume locations throughout the home, the led lights are starting to fail on all of them making the volume number hard to read. I can’t find replacements online. Q: does anyone know of a viable replacement for these modules? Would the Hi-Fi2 volume controls work with the original Hi-Fi?

Thank you.
HiFi 2 VSCs will not work on the old HiFi 1 systems or vice-versa. The LED displays may be able to be replaced but I have never attempted it.
