Hi David, welcome to the forum and back into the Microbee world 
Remove and re-insert the top coreboard a number of times generally helps. Same for any removable chips. I wouldnt raise the voltage above 12v in fact I'd lower it to 10v as the Tant caps near the voltage regulators tend to fail. Have you checked the output voltages of the voltage regulators?
Looking forward to your Premium Plus kit construction story. I have one and is simply the BEST Microbee ever made.
