according to the manufacture they stated JJ for the preamp section
(6sn7) and for the phono section they recommend the Shugan from China.
Anyone with accurate info.
This is correct. With any high performance product using tubes, the tubes have to be hand-picked. NOS 12AT7s that are quiet enough to work in a phono section capable of working with LOMC cartridges disappeared long ago. I'm not saying you can't find some, but they are very hard to find these days. So new tubes have to be used and the Chinese 12AT7 has the lowest rejection rate.
Spoke with Ralph, he wants $2400 for both the preamp section and phono
with caddock upgrades. I think that just too steep for Caddock
resistors!
@zipost ,
@clio09 is correct, the Caddock resistors we use are not stocked by Caddock and have to be built per custom order. They are pricey! But they are also the best we've heard, and one of the best performing resistors you can buy. Vishay now owns Caddock, but has wisely chosen not to mess with them in any way, since Vishay has never made anything with their name on it that performs as well.
