The complete chassis slides out the rear of the cabinet by removing the four 10/32 machine screws on the bottom of the cabinet, do not remove the 4 metal feed on the bottom if they are still there.
Do not drill out the riviets as they hold the chassis together . Why is it you need to gain access to the inside of the amp

The bulbs are a number 335 and can be removed and installed from the front of the amp much easier then from the inside of the amp by using needle nose plyers to carefully remove the blue lens from the face of the switch.
Use some clear tubing to remove the old bulb and install the new one.
Do a search on line for the bulbs, I think I saw some on Amazon.
