Power Supply Mod
Metal Film Type
Carbon Type
~
PROBLEM:
On a few Power Supply Regulator
Boards, the unintentional use of
carbon type resistors instead of
the more stable metal film types
at locations R218 and R219 may
cause a shifting of the +9.6 volts
D.C. from its initial setting. This
effect, which is due to
temperature changes may cause
such malfunctions as:
• Mechanism scanning
• Repeat playing of the same
record
• Displays not on
• Cofns not credited
• No selections
