What valve springs do you use now a days? mine are rattling and do not stay centered, it is a recent purchase so I'm unsure as to what they are but I am guessing standard Yamaha's by the looks of them. Any suggestions TNFJ? I can take pics of the bottom caps tomorrow for a reference. I know they are not original to the horn and have been machined specifically for this tuba.

I second Elephants recommendation

Never knew you could buy rubber coated springs... who sells those?

I use Yamaha springs in my Olds 099-4 also. When I had the valves rebuilt, Dan O. machined a groove on the inside of the bottom caps which would keep the spring centered. The Olds bottom cap has enough meat that machining the groove (about +/- 1/8" deep) was not a problem.

The posts above refer to the clear-plastic-coated springs that Yamaha uses for all of the Yamaha 4/4 and larger-sized tubas. These springs perform better than any others that I have encountered within the size parameters where they will fit. Coupled with a thorough chemical-cleaning and Hetman lubricants, the Yamaha springs seem to last for years with little or no coating breakdown.

... If this was the biggest controversy the world knows, wouldn't things be grand? ...Nevermind, WERE this the world's biggest controversy, we would probably go to war over it. "

You must be a tuba player , 'cause that's pretty deep.
