While checking out the vtvom I found it had 62v ac. between the chassis and earth ground. Did not matter which way it was plugged in.
It has 2 -.25 line bypass caps from the primary of transformer to chassis.
Put an 1000 ohm resistor between the chassis and earth ground and measured across it and have 12 volts. So I cut the ground side of the .25 caps and jumpered in 2-.01 Y-type disc safety caps. It now reads 51v ac chassis to earth ground and.05v ac across the resistor.
Two questions I need help with.
Is the 51v with the new caps a phantom voltage?
Can I use the .01 safety caps to replace the .25 caps or should I order the larger value safety caps?
Any help greatly appreciated.
