Ran into a problem checking the resistors
EX:  Here is a picture of part of schematic..

Part number 33134 say's I think 100 M ohms.  However when measured it reads 100 K ohms.

Here is part list..

the part list say's 100 M ohms..  Does the M mean kilo ohms???  This is from 1937..

All resistors that I thought was Meg ohms all measure K ohms..

Very confusing..  Any thoughts??

Skip...

 The "M" after each resistor value stands for Mill, or latin for one thousand, like millennium. On those older schematics the draftsmen sometimes used "M" whilst others would used "K", notice that the one million ohm resistor above the bias cell says 1 meg ohm. If the 100M resisistor tests as 100,000 ohms that's great, it means that it does not need to be replaced.
  Regarding the bias cell, another way around those is to redesign the circuit, like replace the bias cell and the 1 meg resistor with a 10 meg ohm one, but connect the cathode of the first audio tube to B-, but try a watch battery there first to compare.
