I’m not expecting this one to be overly useful to most but it’s an interesting comparison (to me ) and does demonstrate how materials outside of the plate can effect the sound of a board.
Mechmini 2 with Vintage blacks and Gateron milky tops lubed with 104, sprit 65g springs lubed with 106.
The first is an all brass base I had machined, the second the original PC base from the GB. The board is using a 1.5mm fixed brass plate from laserboost.
I think the difference largely speaks for itself and is as expected. Kind of annoyingly I prefer the original however.
