Help with Speedball upgrade

[Jimb0]

It looks like the terminal at B2 melted the red wire from 7U to B3 and may be touching the inner wire.

Also, I'd check out the sockets again and make sure none of the wires and terminals are touching each other or close to each other. When you put the tubes in they move so make sure they have ample space.

Did you reflow 12U?

Sometimes when you have two wires or more in a terminal one of them doesn't get soldered properly even when you reflow it. I like to desolder suspect joints with a desoldering pump. Then when I'm resoldering I make sure the solder melted properly on all wire tips.

I noticed the melted wire on 7U also, and I've replaced it completely.

None of the socket terminals are touching and I've wiggled them all with the amp on and no change in behavior.

I've reflowed 12U and pretty much every other joint on the amp with no change.

At this point I've run out of ideas, so I'll most likely be sending it into Bottlehead for them to take a look at.  Thanks for the help, though.
