Wurlitzer Solenoid Players
By John A. Tuttle

Hi All,

Regarding the 'pistons' in the tracker bar of the Wurlitzer Solenoid
Players, DL Bullock writes:

"Each hole has a perfectly formed rubber piston with a square on one
end that fills the tracker bar hole so that when at rest the rubber
comes within a thousandth or so of touching the paper."

I was always under the impression that the pistons were made of a carbon
compound. The book calls the substance Delrin. Does anyone know what
Delrin is?

And the contact bar was supposedly coated with gold for long life and
minimum corrosion.

Musically,
John A. Tuttle (john@player-care.com)
