Wave Shield incorrect resistor?

by ants_81 on Wed Aug 22, 2018 9:05 am

Hi there,

I've just assembled my Wave shield, but I wanted to check if one of the parts was incorrect. The online guide says R8 should be Brown, Black, Yellow, Gold - but the resistor I got was Red, Black, Blue, Gold.

I used this resistor anyway, but the sound I get is very weak and distorted. Could this be the cause? If so, I'm happy to pop down to my electronics store to get the correct resistor - but I wanted to check first.

Here are pictures of my soldering efforts:

Unless you can spot anything else wrong?

Thanks,
Anthony.

SOLVED: I went ahead and got a 100K resistor from my local electronics store. Desoldering the existing resistor was very challenging (I used a desoldering pump).

Good news is that the new resistor solved the problem! Sound is now loud and crystal clear.

Lesson learned: Always check your parts list before soldering!

Good to hear you solved that - and found a local source. 20Mohms is quite a bit different from 100Kohms. I'll make sure that the kitting team is aware of the part error.
