Well it is comparing different things really. QC in mass production is far easier than on production by piece. It depends strongly what components are selected to be used and how they are applied.
The only time I got foodpoisioning was in a Michelin star restaurant, never at McDonalds. Why? Because they use different ingredients and apply them differently.
@davidng this crossed my mind too, I wondered if it was to do with the collective electrical characteristics of many smaller capacitors having some advantage over one larger one? Or perhaps it’s commercial? Lots of automated insertion caps verses the installation of a few by hand?
I shall do a little research.
Either way the maintenance/ fault finding and ultimately replacement of lots of caps will be a pain and costly.
It has an advantage with lower ESR since all the caps are in parallel. It is also cost driven. Many smaller capacitors are cheaper than one big one.
The disadvantage is taking up so much board real estate. Yes, the major disadvantage is trouble shooting a problem. Imagine one of those capacitors is shorted. It would be really tedious taking them out one by one till you found it.
Correct. Since they are in parallel, the only way to test them is to pull them out one by one. Some capacitors only fail under full voltage, so just measuring the capacitance is not enough.
Image 7 : Finally - inside - housing and bearings laid bear for all to see.
At this point, bearings can be inspected and replaced, if necessary. As well as housing being cleaned and new lubricant, before re-assembled as above - in reverse order, etc.
My sincere thanks to the brilliant Johnnie

I appreciate this is a little off topic but, I’d love to hear your thoughts on your arm post service. I’m thinking about the same for my Ittok, probably with a rewire too
Hi @audioade. In this case, my much loved LP12 c/w Ittok went in to my dealer for TLC. A “swing test” very quickly asked questions about these bearing and so it went off to a specialist - Audio Origami - for further investigation.
It only natural after 30+ years these bearing might need to be considered. They get a lot of wear.
No decisions were made about internal wiring, so can’t comment on this aspect.
