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.

I recently replaced the 0.47pf coupling caps in my 300B amps with Duelund tinned copper foil PIO. I was so impressed with the results I quickly replaced all the caps in my Trio crossovers. Money well spent. Now I'm working in the phono stage.

  Hi Tam. Your hooked. Once one uses them all other caps just come up short.   Expensive but IMHO worth every penny spent.  Used for speaker crossovers will make one very happy. Try the CAST or Silver versions.
 For the Analysis planars going from Mundorf silver/gold to Duelund CAST copper inductor, cap and resistor was just heaven. Not for the financially shy but if feasible worth every darn penny and then some. Love my caps.
