Help with speedball upgrade

[sparggy]

Hi Guys

I have installed my speedball upgrade after a couple of weeks of using my stock crack and have run into some issues ...

I have tried fixing this myself without any luck. I will list voltages below but a couple of things I noticed first, the LED on A7 from the 9 pin socket has stopped lighting up. also one of the LED lights on the speedball was also not lighting up (D1 on board A). looked for shorts and cant find any so far, also my voltages are off see below:

** Not sure if it matters but I am in Australia so its 240V here

Terminal
1 - Showing as negative 240
2 - 188
3 - 0
4 - 187
5 - 65
6 - should be 0 but going fluctuating between neg 16 and pos 18
7 - 59
8 - 0
9 - 102
10 - same behavior as 6 above
11 -0
12 - 0
13 - 187
14 - 0
15 - 206
20 - 0
21 - 225

Probably should not have done this as voltages were not right, but i did test with some headphones and one of the channels is working fine and the other is not with a slight hum to it.

Also the led thats not working on board A, while trying to fix this I actually screwed up and melted it so nothing is going to make that work

The LED on the small board is almost certainly not at all the problem.  It isn't lighting as a symptom of another issue.

When you get the replacement LED installed on that board, let us know and we can help you debug from there.

Thanks Paul

I will first see if I can source of of the LED's here and if not will order one through bottlehead, only reason being delivery to Aus will take a fair bit of time and it will most likely be a cheap part if I can get it.

Will update once I have replaced it.

Thanks
