[ForSale-Swap] Audio Bandpass Filters

[James Duffer]

I have a "lot" of audio bandpass filters which have never been used.  They 
are in a mermetically sealed case with 4 solder terminals on one side and 
mounting holes (threaded) on the opposite side.  These were obtained in a 
DRMO buy several years ago.  There are a total of 13 units all but one 
marked for 600 Ohms impedance, one is slightly larger and marked for 10 KOhm 
Z.  The units measure 2" x 2.25" x 1.5" with the high impedance measuring 
2.75" x 2" x 1 5/8".  The units have the following markings on them

1.F&W INC, 16605, SMD 548281, Z 10K(Ohm), FO 500HZ, 701 726

2.SMD-548277, F&W INC, 16080-1D, FX4RX22YY, FO 500HZ, Z600 Ohm, 701 724.

3.PGI-725-2, FR4RX22YY, 600 Ohm, 700 CPS, 548277, ADC D10987-1, 66/27, ADC 
A386

4.PGI-725-4, FR4RX22YY, 600Ohm, 1100CPS, 548277, ADC D10989-1, 66/34, ADC 
A398

5.SMD-548277, F&W INC, 16080-5D, FX4RX22YY, FO 1300HZ, Z600Ohm, 701 731

6.SMD-548277, F&W INC, 16080-6D, FX4RX22YY, FO 1500HZ, Z600Ohm, 701 726

7.SMD-548277, F&W INC, 16080-7D, FX4RX22YY, FO 1700HZ, Z600Ohm,701 730

8.SMD-548277, F&W INC, 16080-8D, FX4RX22YY, FO 1900HZ, Z600Ohm, 701 725

9,SMD-548277, F&W INC, 16080-9D, FX4RX22YY, FO 2100HZ, Z600Ohm, 701 726

10.SMD-548277, F&W INC, 16080-10D, FX4RX22YY, FO 2300HZ, Z600Ohm, 701 725

11.SMD-548277, F&W INC, 16080-11D, FX4RX22YY, FO 2500HZ, Z600Ohm 701 730

12.PGI-725-12, FR4RX22YY, 600Ohm, 2700CPS, 548277, ADC D10997-1, 67-23, ADC 
A552

13.SMD-548277,F&W INC, 16080-13D, FX4RX22YY, FO 2900HZ, Z600Ohm, 701 735

These may be components to some existing military receiver, or could be 
handy for some homebrew experiments.  I want to sell the complete lot.
The price is $55.00 including shipping by USPS in the lower 48 states.  The 
boxed filters will weigh around 11 pounds.

Thanks for reading this.
