The PIO RIAA caps relate to the Cornet or Cornet 2 owners. I have 10 sets of paper in oil K40Y9 caps for the RIAA circuitry. Anumber1 posted on a different forum that the Panasonic film caps in 630v are no longer available from Digikey. So these PIO caps would be a go to piece if you are contemplating a C2 kit purchase. RIAA PIO caps for Cornet or Cornet 2 are $6.75 for a set of 4 which includes 2 each of 0.001uf 200v and 2 each of 0.047uf 400v K40Y9 capacitors. I have been using these in my Cornet 2 now for nearly a month with superb sonic results. These come highly recommended vs the Panasonic caps.
Here is the current teflon cap availability:
0.022uf 200v $2.25
0.10uf 600v $4.75
0.22uf 600v $6.75
0.47uf 200v $13.75
I am not sure how many more of these caps will remain available. The teflon caps now appear to be thinning out like the K40Y9 paper in oil caps. If you are on the fence you should buy these soon.
BTW the K40Y9 caps are in such short supply I cannot make them available as a group purchase item at this time. This should be a warning sign. If you want PIO or teflon caps you should purchase these soon.
If you are interested in teflon caps then email me at jim_howard_pdx@yahoo.com for additional information. This will be the final cap order for 2008. More importantly, unless further stocks materialize, these may become harder to find. They were built back in 1990-1992.
Cheers.
