So I've been trying to figure out the TPS on my National. Thanks to Norm pointing me in the right direction that the music search buttons have a mechanical locking mechanism and not an electronic one.
So after stripping the whole TPS down including having to take all 11 switches apart to get to locks which were jammed.
I finally got them unjammed...cleaned and greased everything, plus had to add extra spring because original was worn
Well it's all back together and working great. Every so often the clear button sticks a bit but works
