Radiola III Capacitor Values
8/16/2002 10:14:19 PMPaul Adolph
I have a Radiola III and a schematic but the values of the Caps. are missing on the schematic. There are 4 (1 for each antenna post) and 1 on the primary of the transformer. Do you have any info on what values these may be. Thanks for any info you can provide.

Hi,
Actually there are supposed to be 5 caps based on my info (not Riders), In any event, the cap across the primary should be a .001, Antenna terminal 1 is .0005, Antenna terminals 3 and 4 where the jumper link is located are .00025 for terminal 3, and .00001 for terminal 4. (The fifth is the grid leak capacitor with a value of .00025, terminal 2 leads to this..

Hi

One thing I would like to add to John's posting. The .00025 grid cap has a 2 meg grid leak resistor in parallel, inside.
