I am restoring a Zenith 6-S-128 radio and the schematic has several resistors that are marked m ohms; r2 990 m ohms, r3 400 m ohms and several more are listed as m ohms. 990 m ohms seems very large and I am wondering if Zenith use the m ohm listing as another multipilier value. Any help will be greatly appreciated.

Usually on older schematics the M stands for K ohm.
500M = 500K.

:Many thanks Mitch, I thought that the M most likely was K ohms but wanted to get some additional help.

Roman numerals: M = 1000

Hi Ben,
One thing to be on the look out for is that many Zenith schematics are muddy prints. Some capacitors may have lost their decimal points changing .1uF to 1uF. If you have any 1uF or 2uF capacitors, get suspicious.

All the Best,

Bill
