Making up 50k resistor using 2x100k in parrallel

Postby philrob1 » 02 Apr 2012, 19:39

Hiya folks, wondering if you could help me...I'd like to make this circuit - typical bootstrap buffer, however it requires 1x 50k resistor. These are hard to get hold of, if not impossible, so I'd want to use 2x100k in parrallel to bring it to 50k. Question is, where could I put them?

Is it just a case of adding another 100k resistor next to the 50k and moving the output and bridge across one?
If you could use this drawing, much appreciated!!!

Put the 1st 100K resistor right where the 50k resistor is supposed to be. THen solder the legs of the 2cnd 100k resistor to the legs of first resistor. Piggy backing them works just fine and is not that difficult to do. No need for a pic to explain this one I think.

Either that or use a 47K resistor or a 52K resistor, which are easy to get : ) Or add another column and put it right next to the other one.
