Duelund Tinned PIO Caps
« on: March 27, 2018, 10:56:17 AM »
   All the rave at $190 for .1UF. So to transform my Cyber 211 a pair of .1UF and a pair of .47Uf. So over $700.  :duh Jensen silver .1 and copper PIO .47 a mere bargin at over $600. Thinking hard on this one.
Any other suggestions ? .47 is coulping cap to WE 242D and .1 is input cap.

Charles, what is the following resistor to ground for the .1 and the .47uf caps. (Probably grid resistors)

cheers

The 0,1uf just seemed small unless it was either for bypass, or the grid resistor is quite large.
Otherwise it seems to be working as a high pass filter, ridding of very low frequency garbage.

cheers and all the best.
