Welcome to the Phorum!
Here's the link to the 37-650 schematic on Nostalgiaair.
If that dogbone resistor has a yellow body, white end and yellow dot (i.e. you see no dot because its the same color as the body) then its a 490k resistor. There is a 490k (resistor #53) in the set as well as a 190k (#36). A better set of schematics on the 37-650 can be found on the audiphool site and you can order a really good set from Chuck for just a few bucks.
