@ALFAHOBBIES thanks for the drawing. Did you completely remove the board from the panel and replace it with a push button pot and digital meter along with other components like the power switch?
Can you give me a drawing of the hole it came out of so we can suggest a panel design?
I had this panel inside the lid of the K40, made for the digital one.
But, it had a “membrane” on top to make out the buttons, like a thick vinyl with printed buttons on them.
This fits the digital panel + three switches
Yep, I completely removed the digital panel and replaced it with the pot and meter. I no longer have the panel so I can’t measure it. I also added a push button switch to test fire the laser as shown in the drawing. I made a new panel out of plastic.
I really like the digital volt meter and pot conversion. The volt meter makes it super easy and quick to adjust power now.
@ALFAHOBBIES I´m curious, can you show a pic of your conversion? 
Mine is still hanging in the wires, haha
I’ll post some pics tonight when I get home.
I ordered a big meter by mistake so I figured with my eyes getting older I’ll just use it. I really like the volt meter.
