          As someone who has serviced many various vintage audio equipment for a considerable amount of time, I have developed a deep admiration for good quality gear. However, I have noticed that many of these units suffer from constantly failing incandescent bulbs, resulting in wasted money on services to replace them time and time again. After years of dealing with this issue, I decided to take matters into my own hands and develop an LED replacement that would match the color temperature and angle of the light.
           Through my research and collaboration with a manufacturer of LED bulbs, I was able to develop a perfect replacement that not only matches the color temperature but also offers a 360-degree lighting angle compared to the 120-degree angle of regular LED bulbs. This LED replacement has the correct voltage and is sure to save users time and money in the long run.
        I am thrilled with the results of my efforts and confident that this LED replacement will be a game-changer. Say goodbye to constantly replacing incandescent bulbs and hello to the reliable and efficient lighting of LED technology.
Included:

       2 x fuse 8v LED bulbs
     2 x bayonet LEDs
     2 x Blue filters (For those who want to make the dial look like McIntosh. Optional)

All are LED, literally infinite bulbs.
Color- Warm White

Also available a NEW production volume control for this unit
It is a very good idea to have the original replaced
