[Collins] (no subject)

[Wn4i]

As far as i know ....I have 3   51J3  //  2  R388  // 2  51J4 ///   and the
all the ceramics "dogbone " bypassing capacitors are  very good
......ceramics  are no problems .....only black round papers and some red
micas . .

I first fall in love with Collins with a  51J4 in 1961 ....and my first
KWM-1 in 1962.
