************** Coils ************

28uH Roller Coil, 42 Turns #12, a skosh over 2" in diameter, 8 TPI, 3" x3" x 7" 
overall plus 3" shaft. Fiberglass coil supports. I think that this is the coil 
employed in the MFJ-989 antenna tuner. Excellent condition. $50 

Toroidal Tank coil -- The core is fiberglass & resin encased. It is currently 
wound with 20 turns of #12 wire. There are notches in the form for up to 40 
turns. It is a bit over 4 inches in diameter and about 1-3/4" thick. This was 
made by Bob, W6YUY. See his article in August 1985 Ham Radio magazine "Design a 
Toroidal Tank Circuit for you Vacuum Tube Amplifier". $50

the pair.

Johnson 122-101 ceramic 7 pin septar socket (accepts 826, 832, 4D32, PL6549,
