I Recently found a "spare" chassis for a  41/623 Radio/BOL .  I recently restored a complete unit and thought it would be a good idea to have a spare for parts, etc.    I replaced the rotted out power cord, and all the electrolytics.  and now  It powers up all the tube filaments  but the 50Y3 rectifier will not power up.  I know the tube is fine as it works in my original good working  chassis.  I am seeking some advice on how to proceed.  I would like to get this chassis working if possible.  The transformer does not "appear" to be shorted as far a leaking, etc.   Thanks for reading.
