Calling all 1120 Owners

I have just had the pilot lamp replaced in my 1120 for the third and finally correct time (right part, right voltage, competent repair person, etc) but it is not very bright. I am concerned there is some sort of shroud missing, removed by the first person to change the bulb. Can one of you guys post a close-up picture of the stock lamp assembly? I see light coming through the tone control sliders and I just think for such a clean design this would be an obvious oversight on Marantz' part. If they are all that way so be it. If there is a shroud missing, perhaps I can fabricate something to replace it. Thank you.

Here's a photo of my 1120. It looks like it does have a shroud - made from a rubber grommet. Hope it helps

Well, that is pretty much what I have as well which is reassuring. Maybe the pilot just isn't that bright. It's on and I can tell its on but it's not very bright.

Thanks for posting the image. Enjoy your 1120!

If you add a short piece of aluminum tubing it might make it brighter and reduce the stray light. If you can find the right diameter it could fit between the bulb and the grommet and extend forward towards the faceplate.
 
I have considered doing something like that. I am not sure how hot the bulb gets so I want to make sure I don't burn it out by trapping the heat. Upon further consideration, I don't think I have the black piece with the 1/2 circle cut out which appears to help guide the light toward the face. I already installed the 1120 into the cabinet and connected everything so I will have to investigate the next time I have it open. However, I might be able to just pull the face since I have the unit mounted in the cabinet using the holes for the feet.

I will check it out.
 
When I re-cap my 1120 I'm going to install an LED. It shouldn't be difficult - and a whole lot brighter. If you want more blue, use a blue LED.
 
If you measured 32VDC with no lamp (no load) my guess is that it takes a 28VDC lamp - #757 or #1819 @ 28VDC.
