I Have a smaller (1927) Aeolian Player, The automatic sustain works well - It just dosen't stop working for around 2-3 seconds after operation.
I have 'pumped it out'from the tracker bar to no avail. It looks like a blocked bleed to me ???? Where should I look ?? in the Pneumatic itself or in the top valve box along side the tracking pneumatics.
I'm reasonably practical just not very knowledgeable, and I don't want to pull everything to pieces looking for a fault that I may not have diagnosed correctly.
