How to replace bulbs in McIntosh MX130?

I have got 4 bulbs out on my mx130, three across the top starting from the far left. and one on the bottom, second from the left. I would do and LED kit but I still want it to match my MAC 3.
Does anyone know how to change the bulbs and where to get them (some say you can get them at Radio Shack and others say a TV repair shop?). Do I have to take off the face plate.

Thanks in advance for the help.
