I saw a manual and lots of parts. Not sure if you will find what you need.
They have a 1-800 number to call and ask for the part.

Where can I find a picture tube (cylindrical shape, 1990) and a service
manual for a Sony KV-20EXR10 on the internet? I understand it probably
won't
be worth doing. However, the image geometry of the current flat direct
view
sets is unacceptable to me.

Thanks,
