OSRAM 12V 3W

Is anyone familiar with this "bulb?" What is its purpose? I guess as long as it’s lighting up I should just leave it alone?

It serves two purpose, lower the power supply rectified 40VDC to 34.2V, and also works as a current limiter (something like a reset-able fuse).

Maybe you should contact Synergistic Research if they have any purple audiophile light bulb to replace it.

Excellent. imhififan, you made me laugh😀

Har har.

was there anything by the light that looks like a basketball hoop? Sometimes
The little gremlins that make the synergistic research products work string up a light so they can play basketball when no one is listening to the system

Har dee har.

If you don't agree, then can you tell me what the "bulb" does?

And if you don't like Synergistic Research's products, please don't waste your time replying.

imhififan is ABSOLUTELY correct. It’s like a slow turn on circuit! He really knows his stuff. Sorry if I made you think it was not a genuine response.

I got an initial response from SR saying they've never encountered the "bulb" in this unit. They requested more info. I sent pics of the bulb lit up and not lit. I've had no response back so I'm taking it that they do not have a fuse to replace this. I did install 2 other fuses and the receiver sounds marvelous. I'm content.
