[Amps] B&W 852 Impedance Measurements

[Bob Maser]

The B&W 852 that I bought arrived today and is in good condition.  I took 
some inductance measurements for each of the band positions and found that 
all of them are low as compared to what I thought they should be.

            Original Specs                Actual measurement

10            .95 uH                                   .61 uH
15            1.34                                       .96
20            2.34                                     1.67
40            3.72                                     2.56
80            7.00                                     5.41

My measurements were made on a AADE unit which has always been very 
accurate.  The 852 was not mounted on the aluminum chassis, just sitting on 
a wooden bench.  I cannot see any signs of alteration, it all looks stock.
In order to use this 852, the Q would be between 15 and 20, very sharp 
tuning.  The Original specs correspond to a PLI of 2000 with a Q of ±12.

Any comments would be appreciated.
