Ok, so here it is, as I mentioned earlier I had to mod the ps to bring the voltages down and to make life bearable for the EL84's I got in the sockets instead of the 7189's. As you know 7189's are getting rarer than hen's teeth and definitely non existant down here in Oz.
The voltages are (with actual in brackets);-
Control Grid: 18V (16.2), Cathode: 30V (28.9), Plate: 390V (378), Screen: 340V (331)
In regards to replacing the caps in the Sony V-Fet, I already have a batch of Nichicon Muse, Elna Cerafines, etc, that I ordered from England ready to go in... trouble is I keep on getting sidetracked all the time, like the Fisher, the 6aq5's or your mention of
J_Fets... though this is not your fault, but It just so happens a
friend of mine who is also an audio nut like us came across a neat
little circuit on a Jap site using four 2SK117 J-FET's at;
http://member.nifty.ne.jp/MUTSU/e/hp009.htm
check it out, what I like about this circuit is that there are no caps anywhere in the signal path, at all! And it's simple to build...
one day....
Hope you can help with the triode connection though.
