Are there any Onkyo m 504 amps that are good?

What should I use to repair my Onkyo amplifier?
One issue with this onkyo amplifier is that two of the bulbs that light the meter’s are missing in action The lamps were easy to obtain but I didn’t have the green gel boot that was on the original lamp. I obtained some green lighting gel. I rolled the sheet of lighting gel around the lamp and used adhesive to keep it together.

What does the Onkyo Grand Integra M-508 power amplifier look like?
The M-508 is an impressive-looking piece of hardware, with good, clean metalwork finished in flat black on all sides, and two unusually large (6!9 wide), black front-panel meters. Their calibrations and indicator needles are edge-lit in what might be described as rain-forest green, making for quite a sexy appearance.
