So how do you get the 3 common values of .001, .0022 and .0047 for C3 with a DPDT switch? I would have to use .001 as the primary and add the others in and out to that value in order to get the other 2 ( .0022 and .0047 )? I cannot seem to find the other values I would need to make this happen. If I use .001uf/1000pf to start I would need 1100pf and 3700pf to get my needed values? Am I missing something here? Maybe I'm just guitarded...
