Basically, the center pin "soldering terminal" is a "cup terminal".
He could have heated the cup and inserted the cable into the hot solder, instead the cable is soldered to the outside of the cup. From the looks of it, it might be mechanically stable, and whats important, the little white ring which isolates center from ground does not seem to be compromised. In other words this looks to me like it should work.

I think 3 o clock setting should be way too loud with the speedball in place. Maybe the volume is padded down. Take some pics around the volume pot. Underneath of course.

It's not pretty, but it would seem you have a connection.  Does not sound as if there is a channel imbalance, so the volume concern is not related to the RCA.  Were it me,  I would get a couple of new RCA jacks and have them soldered properly.  My concern is the integrity of the jack, especially the insulation surrounding the center pin. That much heat was likely not a good thing for long term reliability.

Cheers,

Dale stepped attentuator.  I bought this used.

He is of the "Make a good mechanical connection first" then solder train of thought.   Just slipping the wire into the cup makes no mechanical connection.

You are fine.  His answer works well.

That actually sounds about right with the Dale attenuator.  I use them on my Crack and my S.E.X., and they both have to be turned up fairly high.

Great!  Thanks to everyone for all of the tremendous help answering my questions and easing my concerns.  It sounds great so excited to dive into it and if any sound issues arise I'll address them at that time.
