Dear J, Yes, as mentioned, I did talk to Stan Klyne 2-3 times, regarding both the outboard PS that I built myself for my unit and the state of tune I eventually chose for the phono section in my 6LX, which he rebuilt. I agree he is a very nice person; he and I share an interest in Beveridge speakers, and I tried to hook him up with a pair of 2SWs that were then for sale in Canada. My ulterior motive was to get him to take a look at the schematic for the solid state input stage of the Beveridge direct-drive amplifiers.
I've communicated with Mr Park, as well, but only by email and only with respect to a Silvaweld phono stage that I own. He too comes across as a very nice person. However, he could not help me, because he does not have the schematic for my unit. (As you may know, he was the designer of Silvaweld components, before he started Allnic.) Also, I sensed that English is not easy for him.
