Hi All,

Does anybody know a part number or type for the bulb that backlights the main power switch on the front of a Dolby PS1B power supply? I have two PS1B's, both of which either don't have the lamp fitted or the bulb has blown. Both units are working otherwise. Also, how does one extract the push button head to replace the bulb without damaging it?

Best regards,

Mark.

For future information, I found that the PS1B power switch lamps are telephone slide T5.5 x 30mm type. The CP200 schematics show them to be 30V. The replacements I got are rated at 40mA.
