[Hallicrafters] By-Pass Caps-Capacitance Value.

[Olaf Madsen]

Fellow ''Boatanchorites''',

I have ''re-capped'' dozens of ''Boatanchors''--SX-62,SX-28, SX-101.etc. --  
also Collins and National Radios.and replaced the old Paper and Wax and 
''Black Beauties'' types (which the Audiophiles love so much,hi) ---some of 
the radios have 20 plus of these old caps that need to be replaced.

All of them are using   ''By-Pass'' Capacitors for the Screengrid (G2) the 
Cathode and various other areas with Capacitor Values of .01uF or ..02 to 
.05uF.----they are used in  RF as well as in IF and Audio stages.-----

WHAT DETERMINDS THEIR CAPASITANCE VALUE ???----I am sure it is not very 
critical,but is it  done only because''evrybody'' has done it in the past 
and it works,or what .hi.???

I have a bunch of the new ,small ,yellow   Metal/Film caps with  values of 
.0062uF and .0068uF as well as some Disc/Ceramics of .003 uF value which I 
like to put to use.

Tnx for the input which I always receive from this group.----73 de
