Hello Everyone
I've been working an a Emerson 557 http://www.nostalgiaair.org/PagesByModel...004658.pdf

It has a Selenium Rectifier which shows high resistance in both directions. How large a diode should I use to replace this with? the resistor R25 rated 22ohms 1 w reads 29 ohms should I replace this also with a 22ohm This is the first radio I've worked on that has a Selenium Rectifier. Thanks

Eric
