|
|
Earlier this year my Olds Recording trumpet’s valves started to stick on the upstroke, which turned out to be caused by worn valves. As the trumpet played and sounded pretty well (apart from the valves issue) I was initially reluctant to have any work done on it at all. I took it to MG Trumpets in the Netherlands because I knew from previous visits that Mark, the owner, has experience working on vintage instruments. After trying several other options (including new valve springs and heavier oil), it was determined that a revision was the only viable option left. As the environmental regulations have become stricter in Europe, less shops offer proper valve replating, so Mark suggested a rebuild instead.
For the rebuild most of the parts of the original valves were reused (including the top part of the piston), so only the bottom part of the valves were completely remade. Due to the complexity of the work it took several weeks, and the result was very much worth it. The trumpet plays like it came straight from the factory. The valves fit and align perfectly, they run smooth and have superb compression. It’s also even easier to play than it was before the rebuild, with a noticeable improvement in the core of the sound, especially below the staff. The total cost were a little over €650, including shipping, for effectively new valves (and about 25% cheaper than a competitor’s quote for “just” a replate).
All in all I can say is that MG Trumpets has done an amazing job. My Recording played well before, but now it’s amazing!

I can testify of Mark's extremely high quality production. Last year I bought a Bb lead pipe for my Selmer Piccolo Trumpet from Mark, which puts my picc in much better in-tune then when using the A Blackburn pipe _________________ B & H Sovereign 928

That's really interesting.
In order to properly refit a valve, (which is what it's called here in the States) the casing has to be bored cylindrical before the layers of plating are built up on the piston.
If your repair guy actually made a new piston and ports (They do look like brand new metal) for 650 euros that, to me, is astounding. _________________ "Strive for tone." -John Coppola
