I have done the cleaning but she still looses air. I will try to find a rubber conditioner. In the mean time I will do a soap test to see where its leaking from.

Thanks Raul and Etbaby.
Dear Rugyboogie: Please check that on the outside rubber ring it is still all around ( outside the ruber ring ) a nylon thread, if it is good but if loose it then you have to replace because with out it does not works.

Regards and enjoy the music.

The guilty part is the air intake valve. It holds the vacuum for about 30 seconds and then releases allowing air the get in.
Is the inside valve/diaphragm easy to fix, want to know before I start taking it apart.
Thanks again

No did not, decided to put it away to solve another day.
It's been in my heated attic for a bit as the last post was 08.
Time flies.
