McIntosh MR74 bulbs and MC2505 bulbs??

[jgduck]

Can anyone confirm which bulbs are needed for a MR74 tuner and a MC 2505 power amplifier? Would love to swap in new lights for both.

The MC2505 uses the #1866 lamps for the front panel, and #1888 lamps for the meters.

The MR74 uses the #1866 lamps for the front panel, #1847 for the meter, #1828 for the MPX and 058-032 festoon bulbs for the dial.
