the
metal of the front/rear panels. Replace those 2 plus 2 more with same
flimsey 0.1 inch pin spacing switches and try and find or make larger

The 2 off 4PDT switches maybe more resilient to off axis loading so
will
leave as is , unless anyone knows better.


They may well be chinese pattern copies of ALP`s switches, replace them
with genuine ALPS parts and they will be fine

Actually 3.5 mm pin spacing, yellow stem "angle logo", found 4 ALPS marked
ones, blue stem replacements and some slightly larger diameter knobs.
Required slightly opening out the "gold" fascia holes but not the
underlying
panel and unfortunately red in colour. Permanent black felt marker over
them
, cooked in with hot air and repeated again sorted out that aesthetic
problem.





You may find that the yellow stem switches have solder tags on the metal
cover, giving a mounting arrangement that the blue Alps switches do not
have, being all plastic. IME though, the yellow switches are way inferior.

The blue Alps ones are indeed universal and are found in many pretty decent
recording and live consoles, where they give a pretty decent lifespan. They
do not tend to break, unlike the yellow ones, but just wear out. I would go
with Ron's advice and replace with the blue.
