Hi all.
I bought a second hand A 80 controller. i know it’s way too old and obsolete but It’s a good and very well constructed controller and I really don’t need it for poly aftertouch but mainly for piano duties. I feel like this one deserves some good care.
Things work ok in general. But I’m facing a couple of serious issues.
1) Some keys seem to travel deeper and making a louder and very dry release noise (comparing to the other keys) especially the middle octaves (normal since they have been used the most) black ones , like there is very little felt cushion below them.
I know it’s a noisy action overall, but these particular keys sound and feel like there is a problem.
Is there any particular felt cushion I could use to replace the old one? Could it be a plastic-rubber key contact issue? Plastic-rubber contact problems usually have to do with velocity.
2) The previous owner replaced the display with a nice blue one, but for some of the sections some strange characters appear. Could it be a lithium battery problem or something related with the display replacement?
Since I intent on making any repair myself (I have past experience and quite good knowledge and also because of the excessive weight of the controller) please give me any related advice.
Thanks
