Resistor Question

[tungngruv]

I need a 2m2 resistor. Can I just connect two 1m resistors end to end? Will that be close enough? I'm building a DOD 250 and that's the only part keeping me from completing it.

without looking at the schem, im guessing that's a pulldown resistor.
 anything in the area of 1meg to 4m7 should do the trick.
 when in doubt add another 220k to bring it very near 2m2.
 the only place I've noticed large values like that being critical is biasing mosfets or envelope filters etc.
 for pulldown resistors or opamp input ties to V/R, a fairly wide tolerance will probably work.

Yes, it's a pull-down resistor. So I'm clear on this, I could probably use a 1M resistor instead of the 2M2 and it should work, right? You also said  

when in doubt add another 220k to bring it very near 2m2

so I am assuming that I would add a 220K in series with the 1M resistor as a pull-down. Is that what you meant? Thanks, I appreciate the help.

You can tie the 2X1 meg resistor's and get 2 meg, then if you tie a 220K resistor on the end of these you would get 2M2.2 which would be very close to your 2.2 meg you need,

Don't worry about it, since it's a pulldown resistor just use a 1M.  No difference in tone.

Thanks everybody!
