McIntosh MC 752 Amplifier Repair And Restoration

This McIntosh MC 752 is in pretty good cosmetic shape. Not a lot of repair or restoration to do but the power indicator lamp is out.

The lamp in this McIntosh MC 752 power amplifier is accessed by removing the bottom cover.

Then the power supply assembly is loosened so that you can access the burned out bulb.  

I had a bulb shown to the right of the original that I used as a replacement. Soldered it in and used some heat shrink tubing for insulation.  

Bulb replacement was made more difficult as there were no voltage markings on the bulb. I measured the voltage from the power supply.

The power indicator now lights up as it should. The unit bench tests fine and this McIntosh MC 752 repair and restoration is complete.
