Rectifier
1) Using ohmmeter, check continuity between each of upper and lower rectifier bodies and each diode lead (2).
Check both directions by reversing probes of ohmmeter and there should be only one-way continuity in each case.
If check result is not satisfactory, replace rectifier (1).
2) In the same manner as described in above Step 1), check that there is only one-way continuity between both leads
of diode trio.
Condenser
