You almost read my mind there! I also have an MAQ16/3 that is going
to require not only the LED replacements but also the LCD will need to
be replaced with blue as well. Although I'll more than likely see if
Doug at Sonic Highway can perform this task. At some point, I'm sure
to end up in the future with at least one module that has the LED
display so I hope that ordering those modules in blue will also come
with the LCD already replaced.

I'm in the US so I just had Doug order the "official" blue LEDs from
Doepfer for updating my current modules like the A145, A118, A170 and
A127. My other modules already have blue LEDs (and I love them!).

Thanks. I appreciate the advice.

Kindest regards,
