[Heathkit] RE: HR-10B, CWF-2 Audio Filter

[Ted Bruce]

The Vectronics 820K Active Audio Filter is identical
to the CWF-2.  I bought a CWF-2 back in 1972, and
recently re-installed an 820K for a friend.  The
820K's polystyrene caps are slightly smaller in
physical size from the '72 vintage, but otherwise it's
the same.  The 820k circuit board still has "CWF-2" on
the bottom.

73,
