Orange Cable Checkout

Check the Orange Cable (Figure 4.27) for proper seating. It should not be

shorting to the chassis, and its insulation should be intact.

Transformer Checks

The metal sheet over the transformer (Figure 4.27) is at chassis ground, while

the reference box is at guard potential. The two should not be forced together,

making contact with each other, at any point. The transformer beneath the

grounded metal cover is also at guard potential. It should not be short-circuited

to a grounded point, such as the amplifier box next to it near the bottom of the

M4100. An inadvertent short can develop here if the M4100 has been dropped.
