The power transformer for my old Kaypro 2000 Plus buzzes loudly when the transformer is place right side up as designed.
But if I place it on it's side, it goes silent.
Before I open it up, any ideas on what to check either visually or with a multimeter?
Specs:
CHARGER -- P/N 81-1190-1
INPUT: 115 VAC. 50/60 HZ. .24A
OUTPUT: 7.3 VDC. 2A
It has a 5-pin din power plug into the computer. (positive and negative to charge battery? Positive and negative to power pc when battery low? One ground?
