Hi
I rebuilt a "CIBOT" / "MERLEAU" DIY tube amp about 2years ago. The amp is now playing music, yet, one thing that doesn't work is the "power indicator" / "power light"
From the schematic of the amp and the measurements, this is 6.3 volts AC.
Yet, i can not figure out which type of lamp i should put inside the indicator (orange part) or if the orange plastic was supposed to light up (doubtful as it is plastic looking and from the 70's)
The orange part (with metallic butt) is screwed in the panel thread.
I don't know if i am supposed to put something / a lamp inside the orange part or replace it by a lamp.
Thread seem to be roughly 5mm
(I can find infos on similar devices from guitar tube amp, but the dimensions are much bigger each time, at least from what i could find on the internet)
Does it ring a bell to somebody ? A name / spec for those kinds of panel indicator which would lead me to the remplacement part ?
Thank in advance and have a nice day.

I'll make an educated guess. From the looks of the panel socket you need a miniature single contact flange base. Or possibly a sub-miniature flange base. You will have to accurately measure your screw in part and then peruse this catalog and hopefully find a suitable lamp. You'll need to spend some time looking. Another option is to replace the entire assembly with a modern LED type.
My guess is that you need a 6 V Midget Flange Base Lamp, but you would have to check the dimensions.

Thank you very much!
From the Sylvania catalog, i would go toward the sub-midget base. Having a flange kind of make sense with the device.
I will be searching through the internet for that.
Thank again, i could never know about the "sub-midget" dimension without your help!
(i could also make a new specific indicator, but for the time being, i wanted to keep the amp in the state i got it)
