Correction (DUH)
Upon actually *remembering* how my 618F is set up, Collins silk screened
"Warning -12 Volts" and "Warning - 24 Volts" on the power supply chassis in
2 different places. You just relocated the nameplate OVER the warning
label that does NOT apply to the voltage you have set up. Just took 2 extra
threaded holes for the dataplate.. still, a clever, cheap solution...
Ain't Old Age great! LOL
