question about vintage mx blues

[keycap]

got what appears to be some old unitek keyboard with highly inconsistent mx blues, board itself is in decent condition, nothing terribly wrong with it or anything. about three quarters of the switches don't click, they just make a hollow rattly noise if any noise at all

are all vintage cherry blues like this? they feel like mx whites but even more heavily lubed to the point that ALL of the click jackets are sticking. i mean, i never intended on using the board, but this is just so bad

[keycap]

to be fair, they are at least smooth!...but they still feel and especially sound awful!

[Bruek]

the hollow rattle IS the click. they're quite awful switches. weak tactility, awful click sound, nothing good about them.

MX Blue was "vintage" before 1992 or so. It had a weaker bump/click, but the older, the more consistent, at least unused (until the recent retooling).

Perhaps you can get some cheap Bsun blue switches off of Ebay and do a stem swap. Bsuns seem snappier than Cherries.
