Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

Both switch modules locktited inside the nut thread and then applied another coating outside.









Small acid leakage at the power I/F board but not too bad.











The display.
Unfortunately, already something trapped and scratched the internal side of the front clear lens and very likely to be scratched the display module as well.












And yes indeed, the damage was done but will clean this as much as possible.















At least, looking far better after cleaned and disinfected around the front panel.














Cleaned the cassette module around the head and pinch roller.
Apparently, cassette is coming back and potential new trend but not sure it will be like the recent come back of vinyl.
