What is the pressure at the resivoir to the stack compared to the roll motor What is the pressure at the tracker bar with the T bar taped? Was the chest sawed apart to do the rebuild? Maybe all you can do is check for loose screws there. Then with a stethescope check for leaks still there. Listen to each valve (again with the tracker bar covered) If the valves are leaking the chest has to be take a apart again. Which is one of the main of many headaches in a Gulbransen. Run a test roll. Note the weak notes. Run it again and listen to the valves. Let us know what you find. ---ric ----- Original Message ----- From: Paul <tunenbww@clear.lakes.com> To: <pianotech@ptg.org> Sent: Friday, January 19, 2001 8:47 AM Subject: Gulbransen player List I've got a Gulbransen player in the shop to clean up for sale, recently rebuilt by the late William Gilstrap (passed away about a year ago). Beautiful work! Very clean and neat. I don't know what has been done since the rebuild. Everything appears to be in order: cut off and accelerator valves working, motor running as smooth as possible, hoses tight. But, low volume and slow speed. A suction unit was added and works but sounds like it's working at its max. Pedaling fast barely turns the roll. Paul Chick
