Missing part?

[eddhartwellmusic]

On page 49 of the manual, it says to insert 100k ohm 3k resistors, but I don't seem to have any that look like the picture on the page... is it possible they have been substituted?
If so, to what?!

[Paul Birkeland]

I would recommend getting out your multimeter and measuring the resistance values of the larger resistors in the kit.  They will be substituted with another pair of 100K 3W resistors.

From what I can tell, looking at the parts list, these might be the ones!
I'll get the meter on them later

Yeah, those are the ones.  I recently completed mine with same replacement part, pic attached.

[Chris H]

Sorry, wrong pic but you can just see them over the heatsink. Brown, black, yellow, gold is 100k

[Deke609]

Brown, black, yellow, gold is 100k

And here's a chart showing that. It also shows that the gold band indicates +/- 5%.

Brown is 1, black is 0, so that makes 10. Multiplied by yellow, which is 10K, makes 100K.

But I prefer to measure with a meter. Especially with 5% tolerance parts, it can be interesting and informative to find that the values of two "identical" parts are significantly different but within tolerance. Ruling out soldering mistakes, this can explain why the voltages on one channel are slightly higher/lower than the other.  I used to be perplexed by such voltage differences, figuring I had a bad joint somewhere that was adding resistance.

I can't tell resistor colors apart.  One thing I do is the measure all the resistors in the kit with my DMM and lay them out in order.  Maybe this could help you on future builds.
