Just got back from visiting Jim Prior. Some here may know him - woodwind tech at Mayalls and Just Flutes in Croydon and formerly at Ackermans in Hove. He lives a couple of miles from me which is handy and works from home.
Left the YAS-25 for a strip down and full service. The upper stack pads are hard and dry, G# is flaking and the bell pads are a bit manky. Otherwise it's in very good shape! It'll probably cost more than the sax itself (I got it for £200) but worth it to get it in tiptop condition again.
I'll update when I get it back in a couple of weeks.
P.S. If
@Stephen Howard is reading this.........the horn was playing fine when I put it in it's case last year on getting my tenor. After about a year of resting it is now in the state described. The case is in my study, at ambient room temperature (~17-21°C) and the horn was put away cleaned and dried. Am I doing something wrong storage-wise? I did find a packet of silica-gel in the case, could that have made it too dry?
Thanks.
