All Maplenoll owners

I 'd like to share my recent experience with maplenols's owners. I read many times how difficult is to cvlean the small holes inside the air chanber of Maplenoll's arm. I tried to do this with my Maplenoll tonearm when I needed to replace the air pump. No problem with the platter it is very easy to suspend it ; at the opposite the tonearm need a higher pressure. So after I bought a new pump( Takazugi 80) and I realized that the air was not enough for the arm I decide to check if the holes inside was patent and well functioning: to do this a removed the black metal block where the horizzontal arm ( piston) is inserted and after to have inspected the plastic plug wich connects the air tube to the base of the black block, I removed the cylinder ; it is not difficult just use an hammer and give some well addressed bit to the external ring ( Pay attention to not damage the internal surface). The cylinder it is hold in its position by two 0rings.After you have removed the cylinder you can see the holes where the air pass trough the air chamber to the internal surface of the cylinder ; they are four for each side . Now you can unscrew the screws inside the holes , clean them with thricloroethilene and then replace them. Remove the 0rings and subsitute them or simply clean them ( Do Not use or touch them with thricloroethilene): put a little amount of grease . After that you replace the screws and if you want a little bit air more ( this was my case)after you tight the screws turn them back for an hafl round. Replace all and try . To have a better air distribution is better to separate the two pipe line outside the tuntable creating an Y and put on each a meter to measure the air flow.
