How do you check a bridge rectifier in circuit to be absolutely sure it
needs replacing. Conditions: No power applied as 2amp fuse in the
transformer primary blows immediately power is applied. Usual short circuit
procedures followed throughout but I don't place too much reliance on this
test . BTW, the rectifier (B40 C3200/2200)) is in a theatre organ purchased
from an outfit no longer in business and space on the pcb is at a premium
and discourages using single diodes.
