Accordion drone

[missofori]

Hi,

I was recently bought an old Rigoletto Accordion from an auction house to learn so I can play it in a ceilidh band. Some of the sound holes don't have a netting/grate over them, but apart from that, tuning doesn't seem to be a problem and none of the material on the bellows is ripped. However, most of the time, it makes a very strange droning sound underneath the notes (I only usually play the right-hand/piano notes). There is an accordion repair shop nearby, but I'd be quite interested to know what it is and roughly how serious the problem is.

I don't know how much information is needed to suggest an answer but please do ask if you need more of it
Thanks so much in advance!

Try operating the bellows with no keys pressed. If you still hear the drone a bass or treble pallet is leaking (open) so when the bellows are operated that note sounds continuously. If so, try each key/ button individually in turn until you find the key that matches the drone. It'll be the pallet attached to that key... but it may be more than one.
