with technology is always like this :neutral_face:
what about the SID chip? what about the components used in the original MS20? what about… the list could go on and on i guess but that’s normal.
your friend is right in asking the question, no doubt, but there’s not much that can be done i believe and as monk says: ‘just be happy its working now lol:smiley:

ps: you mention that ‘potentially’ roland stuff can last forever, easy to service, still easy to get off the shelf parts ‘apart from CPU’s and swtiches and pots’, which to me are also important components; well, at least with Elektron stuff i’m sure in 20/30 years time you’ll still be able to find all this tiny SMD components, that’s just the way technology goes… just my 2cents…
