* TR16: Pianos earlier than serial #102905 use the MPSA06 transistor.
Starting with
serial #102905, the MPSA14 transistor is used.

|
|
All replacement transistors are current production parts
with the same lead arrangement as the original Wurlitzer transistors.

LEAD ARRANGEMENT: (Bottom Views)
|
|
VCBO - Maximum collector-to-base voltage with emitter open.
VCEO - Maximum collector-to-emitter voltage with base open.
VEBO - Maximum emitter-to-base reverse voltage with collector open.
IC - Maximum continuous collector current.
PT - Maximum power dissapated at 25 degrees Celsius.
hFE - typical DC current gain for a common emitter configuration at
the current shown.
