bridge rectifier
have a bridge rectifier mb10s
120vac 50hz supply has what looks like a 220ohm resistor in series on 1 leg of the mb10s - when I replace the 220ohm resistor 1watt it cooks/smokes on power up??
shouild I be looking further in for a fault??

Without seeing the circuit, check the bridge rectifier for shorted diodes.
I take it that you have checked for a short circuit after the bridge rectifier or stuffed filter cap.
replaced the filter cap was supposed to be 10nF but was 106nF & replaced ZNR1, now she fires up ok
You might have more success if you post some pics of the device, and any circuit diag you may have. 10nF is not a filter cap, 106nF is still too small for a filter cap. You may be misreading components.
