The two pins of the mains plug.
2) Set the mains switch the “on” position (keep
the
Mains cord unplug).
3) Measure the resistance value between the
mains
plug and the front panel, controls, and chassis
bottom.
4) Repair or correct unit when the resistance
measurement is less than 1M Ω
5) Verify this, before you return the unit to the
customer/user (ref. UL-standard no. 1492).
