Aircraft actually had 28V systems.

Subject: [ARC5] BC-454 Conversion


As a kid I had an Arc5 receiver that I used as a Novice.  Recently I came
across an unmolested BC-454.  I am interested in converting it but at the
same time not hacking it up.
So I have a number of questions that perhaps can be answered before I
proceed.

1.  The original filament circuit was based upon 24 volts.  I have access to
a number of 28 volt
     transformers that would work fine but I would need to know what value
of resistor to use to
     drop the value to 24 volts?  This would keep the filament wiring
intact.

2.  I would like to make connections to/from the receiver through the
existing connector.
     Are mounting plates/connectors available or scarce?

3.  Does anyone have a dynamotor that is not working that I can use the
shell and plug
     as a means of making power connections through the 3 prong connector?

4.  How is speaker audio obtained?  Does the output transformer have to be
changed?

Thanks for your help
