The Collins 30W reproduction unit that I am attempting to duplicate 
continues to move forward.  Now I am trying to assemble the power supply 
parts for the 500BX type.

I am looking for two transformers for the power suply that are of the 1930 
design.  The voltages that I need would be about 600 volts each side of 
center tap and 350 volts each side of center tap.  Also the high voltage 
transformer has a 7.5 and 2.5 volt rating with the low voltage transformer 
has 5 volt and 2.5 volt rating.  These filament windings are not that 
important.

The transformer has a cover on each side with open laminations.

I know that this is not much to work on but would appreciate assistance.

Thank you
