Help needed with amp power indicator bulb

[Tiga]

The bulb in this Fender Princeton 65 SS is out. It doesn't look like the bulb is removable or is it? Do I have to source the whole bulb/harness assembly? Thanks for any help!

Hard to tell from pics, does the wire and socket maybe push out from the plastic bracket?

Measure the voltage & replace it with an LED & resistor in series (size of resistor depends on voltage) either AC or DC supply will work. It will last as long as the amp.

It looks to me like it already is an LED, although I could be wrong. It's rare for LEDs to die, but I suppose it's not impossible.

Well I pushed on the bulb a bit and now it's working. Not sure if it just wasn't seated correctly or what. I guess we'll see how long it lasts.

According to the schematic, it is a T-47 'bayonet' type bulb. These are the typic Fender indicator blulb and are notorious for needing to be 'nudged' to make contact. They are pressure fit by a spring and held in place by two nubs and corrode in that position. Moving them around and reseating them usually fixes them, although I have one with an old 60's socket that I constantly need to rap the top of to get it back on.

To replace: push in, turn it left and it should pop out. To install one: push in, turn right until it stops and let it pop up into place. Easy-peasy.
