    I did a bit of searching the forum before posting and did not find an answer.

    I just replaced the right-most #1866 2505 panel lamp with a new #1866 panel lamp. But the new lamp is longer than the old one and it sticks out a little bit more into the diffuser. This causes a bright spot in a couple of the letters in the word "POWERAMPLIFIER" on the right-front panel. I also worry that this might over heat and melt the defuser.

    I measured and the original (burned out) bulb is 1 1/16" (1.0625" or 27 mm) long. The new replacement bulb that I bought at a local lamp shop is 1 3/16" (30.2 mm) long. All other parameters seem to be the same.

    I went shopping online and looked at about 5 or 6 brands of #1866 bulbs and all were 1 3/16" - too long.

    Has anyone else had this experience. Any ideas where to get replacement #1866 bulbs that are 1 1/16" long?

    (If not, I will call McIntosh and / or Audio Classics on Monday.)

    Thanks,

    Both McIntosh and Audio Classics reported they have these panel lamps and Audio Classics specifically confirmed that theirs are the proper size. So I just ordered a few of the correct bulbs.

    Thanks,
