Ok so I have not been impressed with the valves on my Getzen 300 and since it is 1970's model and was abused I chocked it up to worn out valves. Well first the valves look great. Second when I measured them they come out preety darn close to spec.! OEM specifiaction is .650 and I get .651 top and bottom of each valve and .652 in middle. So we are talking a very very tine hour glass shape. I do not recall the radial run out off hand but let's just say all the valves are close to perfectly round. Why do the valves not feel so hot to me? Their are no dents int he valve case at all. My guage set is not small enough for me to use on this to check the bore's I am going to get a smaller guage set from Vota Tools soon. I have cleaned this trumpet a bunch of times and the bore's do not visualy look pitted or have any other defect that I can discern witht he naked eye. Am I just being too picky maybe? I am so used to hearing how great Getzen valves are but really so far my Reynolds and Holton's all have better feeling valves. The Getzen has not stuck since I last worked on it but they just do not feel solid to me they feel fast though. I just ordered some Alisyn Valve Slide Key oil. This stuff is viscous and synthetic so maybe that will be all they need. I fired off an email to Getzen. I do not think my trumpet is under warranty because they only started that 10 years ago and they did not make the older models retroa actively life time warranteed. I wish they had though. My favorite metal detector company Tesoro did that they went to a lifetime warranty and decided that anything they ever made would also be warantied for life. Now I only buy their metal detector's. It helps though that they make a world class product and that it is made inthe USA as well. I wish Getzen had done this. I will let you guy's know what they say. I would even pay them to take a look at them. I would rather have the OEM look at them then someone else. The small amount of wear seems rather insignifacant to me??
