Hello:

A friend of mine has a King 607 student level trombone with an F attachment. The rotor cover is missing, and they would like to replace it. They tried ordering a part through Allied Music Supply, but they have had it on backorder since last June.

Does anyone have any other ideas? Other options to buy a replacement valve cover, anyone who has an old parts horn, anyone who might manufacture one, etc?

Thanks in advance for your insight!

Thank you, Brad! I happened to see that ebay post a few minutes after I posted here, and I think that my friend ended up getting the part she needed! I appreciate your taking the time to point me there as well!

Hello:

Back with another question... So...as mentioned in a previous post, my friend was able to buy the rotor cap. When she received it, she found that the threads do not match and she can't screw the cap onto the horn. Any ideas/suggestions? I am guessing that the horn and the part she bought were manufactured in different eras and the threading has changed. Any solutions?

Thank you in advance!

There are indeed two types of rotors and consequently rotor covers. Unfortunately, I can't shed much light on how to procure a new one w/o having one available other than the two types of valves are quite distinct. One has an angled port. If you can post a picture, I might be able to point you in the direction of someone who has made a delrin one for me, for that model 607F. I can't guarantee if it would work, but I'd put it's success at about 90% assuming they still have my pattern on file.
