Speedball upgrade issues (resolved)

[emilca1!]

Hello,
Upgraded to the Speedball and finished today. Initial voltage/ resistance checks were ok.  Plugged into my dac and headphones.  Ran for a couple of songs for testing.  Then there was a large pop. Music is not audible unless you turn the amp all the way up.  Went back and checked the voltages and everything is higher and out of range:

Small board
OA 182.7
IA 187
B-A/B 0
IB 186.9
OB  182

Large Board
OA 181.7
OB  181.2
G 0
B+ 188.1

Any ideas for help?

Thanks

Does the 12AU7 glow?

 

[emilca1!]

Yes both sides.

What voltages do you get a A3 and A8?

 

[emilca1!]

A3 166.8
A8 151.9
Just noticed both leds out

You have a loose wire in your amp.  This loose wire doesn't really have anything to do with the Speedball.  I would most strongly suggest that one of the black wires at the headphone jack is loose, but it could be elsewhere.  At the bare minimum, one of the black wires in your amp isn't well connected.  It could also help to post some build photos.

Ok I’ll reflow the headphone jack connections. When I built the stock crack I had some issues where I had to reflow them abs then things worked out. Maybe I bumped the wires when cutting the capacitors or putting in the standins, especially the one by the 12au7 socket, that was really tight.  I’ll post pics in another message and start reflowing connections.

Having problems uploading pictures from iPhone. Getting an error every time I submit.

you might need to shrink the file size.

Could also be the format the iPhone is uploading in. You could create an Imgur album and then post the link.

I reflowed the joints and got it to work. I think the standing post by the 12au7 socket knocked a wire. Thanks Paul for the guidance.
