Don't sell yourself short here Marty, your work on this machine has been excellent.

T2 and Flintstones have great appeal to me, and I'd love to see your T2 when done. Flintstones is a great title, and Wotto's was just a 10/10 machine. Good choice !

GI problems are almost always connectors, or dry joints on the GI connectors on the boards.

I agree re Wotto's machine.  From his website those photos of the machine look unreal.  I'm still yet to play a Flintstones.  Next time Mark gets one I will have a game or two.

The G.I connectors on the PCB and header pins look like they had been replaced.  Given only those had been disconnected I thought it was a connection problem at that end, rather than the transformer which had not been touched.  I will continue to monitor. 

What do you think I should do re mylar around the posts - in particular the slings?  Should I cut it away or leave?
