2SC1946 28 Watts FM-broadcast (87,5-108MHz) rf-amplifier
========================================================

All component values are drawn on the .comp and .silklayer bitmaps, with the following
exception(s);

1.- all four (4) coils (in the lowpass filter section) are:
    3.5 turns, 8 mm DIA., 1.2 mm CuL closewound i.e. no wirespacing.


Notes

CuL = magnetwire, enameled copper wire, insulated (rigid) copper wire e.t.c..
(Note:	2 mm equals approx. to #12 A.W.G  
	1 mm equals approx. to #18 A.W.G
	1.2 mm equals approx. to #17 A.W.G
        0.8 mm equals approx. to #20 A.W.G
	0.3 mm equals approx. to #28 A.W.G.)

(I)   all diameters are measured from the inside of the coils, i.e. 'internal' diameter.
(II)  make sure to mount the rf-transistor on a appropriate heatsink and use some thermal
      heatsink compound between the flange of the transistor and heatsink!
      (Thermal resistance heatsink at least 6°C/W.)
(!)   by the way, it's always smart to study the 2SC1946 datasheet for additional 
      information
