It has been a while since I had changed them on a MC352 and MC7205. But I downloaded a service manual to see how you can get to the bulb rail. I am assuming you are talking about meter lights? But once you have the rails or light strips out you must be careful not to get anything too hot removing the old bulb and installing the new bulb as well. Excessive heat can damage the strip/rail. I would also suggest that you replace all the bulbs as if one or two has failed the rest are not far behind. As another suggestion, contact Audio Classics as they may have a LED kit for your amp and this would be the last time you would have to replace bulbs.
