[ARC5] BC-221

[Richard Knoppow]

     I think BC-221 frequency meters are on topic on this 
list, otherwise my apologies.
     I just fired up my BC-221, which has been in storage 
for many years and am pleased to report it came up fine.  I 
brought it up on a metered Variac, no smoke or odd noises or 
smells.  Mine is in a wooden case with an RA-133A power 
supply in the bottom.  I have the original calibration book 
and headphones. This one was made by the Allen D. Cardwell 
company.  The supply has a stamp indicating it was MFP in 
December of 1948, the label has a contract date also of 
1948.  The meter itself and the case have contract dates of 
1945 on them.  This version has a built-in modulator. The 
case and the calibration book both have schematics for the 
main chassis but not the power supply so I will have to look 
for one.  Also, the power supply is just sitting loose in 
the bottom compartment, I have not looked to see if there is 
some way of fastening it down.  The front of the bottom 
compartment has a hole with a couple of fender washers which 
I assume was for fastening a battery in place. Perhaps 
someone here knows.  Its been at least fifteen years since 
I've had this thing out and fired up.  I have no memory any 
more of where I bought it or how much it cost other than it 
was probably fairly cheap or I would never have gotten it.
