Mcintosh c2200 display backlight color

A seller on eBay has the 2200 LED kit

I have had the Ebay led-kit in mine for couple of years. Installation was pretty easy, but quality of the leds was a bit questionable. First led started blinking after a month and few more are dead by now too. Got no response from seller when I asked. There were no extra leds in the kits then.

I’ve been planning to order a bunch of 14V leds to test and try which ones are best, but been a little lazy and still haven’t done this.

All in all, it was a nice upgrade and the preamp now runs quite a much cooler, which is nice.

I put all three gel filters in the meters and the shade is bluer than on my MC402. I kinda prefer this colour more. I should also replace filters on my MC402, as the right channel has a different tone than the other. This is propably from heat and the heat was from the time I had Lyngdorf RP-1 in my system.

Please tell me, it's normal that the backlight color of the arrows of the Mcintosh 501 monoblocks is bluer than the backlight of the arrows of the Mcintosh c2200 preamplifier. On the preamplifier, the color is less blue ... In the photo it is not so striking. Sorry for my bad english. Thanks for the help.

At a minimum, you could have Audio Classics change out the incandescent bulbs and replace the blue film...which tends to degrade overtime from the heat of the bulbs. Pretty easy fix. Probably won’t match your 501’s exactly, but will closer for sure.

Instead of changing the C2200 backlight, you can adjust the backlight of the MC501s to be less Blue to match your C2200. Download the MC501 Service Manual and it shows you how to adjust the backlight.

Thank. Didn't know that on 501 you can change the backlight level ... Can't find a guide on how to do this?

Autosky,

I found a manual for the MC501 here on the forum https://www.audioaficionado.org/show...62&postcount=2

Although it doesn't have specific instructions for adjusting the LEDs, on page 12 of the .pdf (labeled pages 19 and 20) it does show the PC board and the individual blue and green color trimmers, I believe this is located on the front panel between the meters.

Yes. This is the guide.
