Somethings getting lost in the ether here !!

I asked the question because you may have been replacing the upper focus element for all I know and i am trying to determine whether there is an other piece of glass/plastic in the optical system
immediately below this. if you did not understand the query I apologise

I have since taken apart the Aiwa bookshelf system and Ironically this
has a Sony ST***** laser pickup . However this did not enlighten me
either because underneath the focus element in this pickup is a 1/4"
dia tube which you cannot see down without removing the whole
focus lens and coil system .and since this was a working system Ishall reaasemble it and hope it s still working .Aah isnt technology fun!

I did not understand the nature of your question, as you didn't mine.

I did not look to far into the Pioneer head to see what other optics there may be. So it was just the objective lens. The optics may vary from brand to brand.

Well it's not really very ironic?, the vast majority of CD players use Sony optical assemblies.

Also, Aiwa is now 100% owned and run by Sony, and for many years before 100%, Sony owned a controlling interest in Aiwa.

Hi Nigel,
I bet that's a surprise to many.

Strangely in Canada, Aiwa was terrible for parts and service while Sony was much, much better.

If you are lucky, these days your CD has a Sony transport. Technics seem to be very good also.

Aiwa used to be OK for spares in the UK, although not as good as Sony. Now it's the same, as they come from the same place (actually in Belgium) - unless you want an older Aiwa part, Sony only seem to list spares since they took over?.

Of course! There was an opportunity to reduce costs and deflect blame.

Most companies here have a so-so spares level compared to the good old days. Many only have stock for a short time (no where near the 5 year mark they should have). Cosmetic parts suffer the worst.

It's clear the collective "they" do not want their products serviced, but rather replaced. This is very bad for the environment and hastened the RoHS nonsense. This may have been solved in a more productive fashion. I shutter to think what the combination of inexpensive Chinese manufacture and lead free electronics will do to reliability. The customer is about to get it right between the eyes - again. Certainly until they get things figured out again.
