I am trying to salvage a Yamaha Flugelhorn that has a badly damaged valve block - not repairable, replaceable or playable. Before it goes for scrap, I wonder if a Bb trpt valve block would work in place of the damaged valves? I realize that the flugel mouthpipe enters the first valve and the trumpet mouthpipe enters the third valve. Does that make a difference even if the tubing were to be rerouted? I'd appreciate any insight from anyone who reconstructs/refurbishes brass instruments.

Yes, it will work. It doesn't matter which entry point. The difference some may point out is the bore...flugels generally being smaller. Yamaha's student flugelhorn is actually a ML bore and plays great so it can and has been done. They use the same valve block/section as the the student trumpets.

Two observations about the YFH-231.

Does anyone here know the exact bore size? I cannot find it’s specifications online, but I don’t believe it’s ML .460”.

Second, the 3rd valve slide needs to be very short draw or it won’t clear the bell. I know this because I was asked to convert the 3rd slide into an action slide, not easily done because of this. Come to think of it that’s when I realized the tubing size was not the same as a YTR-2320.

You would have thought this was a safe assumption, but it wasn’t.

The Getzen Capri flugelhorn on the other hand shares the identical valve set and slides as the Capri trumpet valve block. With its much wider wrap there’s no clearance issues with the bell.

Good luck!

My understanding is that my old YFH-231 is a "medium bore," .445. I don't have any way of measuring that with calipers or anything.

In the mid sixties I was playing Getzen trumpets and spent a lot of time at the factory between road trips. Sandy Sandberg was the main sales/pro rep and was responsible for getting Doc Severinsen on board with the Eterna Severinsen project. I had mentioned to Sandy that Yamaha had just come out with this student flugel and it played quite well albeit with a bit "lighter" sound quality. I asked Sandy if their shop forman Merle Heuerman and I could take the existing Eterna bell and leadpipe and use their excellent .460 valve section from the Eterna trumpet (same as the Capri) and come up with a comparable student flugelhorn within the Capri line. We did and Getzen kept that model flugelhorn in the line-up until last year and Yamaha has also dropped their model as well.

Knowing how well those horns played I felt the time may be right for my little company, Scodwell USA to re-introduce a similar flugelhorn at an affordable price for the occasional use by trumpet players not needing a $3000 horn. I have mine listed at the moment on the Marketplace and my website where you can see photos of it. Plans to exhibit at ITG this years with this "Euro" model flugel and all my other instruments were cancelled for obvious reasons and hopefully this serious crisis will be solved in the near future.

My mistake on the ML bore, it is indeed a .445 bore
I found specs on a couple websites and compared it with a 9830 and 9610, all identical.
