TUBA SERVICES

Chemical cleaning

• per piston valve - $70.00
• per rotary valve - $75.00

Dent Removal

• With advanced techniques, we are able to take out large dents in Tubas and Sousaphones in half the time. We have the capability of removing most dents without disassembling an instrument, which is time consuming and costly. Please contact our staff for your specific dent situation.

Venting

• Venting valves is useful for trumpet and tuba players. It involves drilling a small hole in the casing (rotary) or valve (piston) so that when the tuning slides are moved the air pressure can equalize before the valve is depressed, preventing a "pop" from upsetting the player's embouchure. The cost varies with the complexity of the job. A simple venting of a trumpet or tuba piston costs $25. The charge to vent a rotor is $30. If the key bridge needs to be removed to enable the hole to be drilled straight an extra charge will be made.

Complete Valve Service -$125.00 per rotor

• A valve service is a complete mechanical tune up for your valves. It begins with a chemical cleaning service. Next, the valves are adjusted to remove end and side play (end play is what causes the annoying click). The bumpers are replaced with permanent neoprene, the lever hinges are tightened, the levers are adjusted to provide the optimal valve action, and any worn or missing screws are replaced. (There is a extra charge for removing broken-off screws.) Valve services can usually be done on a same-day basis with an appointment.

Piston Re-plate and Fit - $300.00 per valve

Convert to Nylon Linkage - $70.00 per valve

Convert to Mini-ball Linkage - $120.00 each (two link-ends)

Bearing Adjustment - $65.00 per rotor

Valve Stops - $20 per rotor/valve.

• We offer valve stops in a variety of materials: synthetic rubber in three different durometers (hardnesses), a soft natural silicone, and a clear silicone-like synthetic. Unlike the shaped bumpers used by some manufacturers our materials are round in cross section. When properly installed they don't break or compress. The harder bumpers give a very positive feel.  Softer materials feel more forgiving under the fingers and are quieter. Our bumper installations include shaping the stop plates to hold the material firmly without compressing or cutting the material and carefully aligning the valve ports. When properly installed, synthetic bumpers do not bounce or "flutter". - $12.50 per valve.

Resonance Enhancement - $275.00 (3/4 instruments or instruments with removable bell only.)
