Rick,
Yes, the reason most folks come here to AudiogoN is to buy/sell gear, I agree.
However, how else can you explain your comment in the original post?
I hope there is some owners out there, my search did not bring up much information.. in fact, there is not much on the net period about this preamp.
You may not notice that newer gear gets much more press on the web than vintage gear.....but you are only fooling yourself.
I originally replied only out of my respect for VAC gear, which I own and enjoy. I'm sure your CPA-1 mk III is a great preamp, and a steal for the price. I'd recommend looking for some Pope or Amperex Bugle Boy 12AX7's, and maybe 12AU7's too. I'm a fan of Amperex, though I do like Siemen's and Telefunken's too. Mullard's are a bit too warm for me. I'd also recommend a Amperex white label PQ 7308 for your 6DJ8 tube, and of course I'd recommend some Herbie's Tube Dampers........now, about the power cord.....I digress.
Cheers,
John
