A few more details, please - what`s the Ia and Ig2 per 12BY7, (and CCS current - the sum of this, x 2 tubes). Then, Rg2 value, Rg2=((B+)-90)/Ig2.
Did you "breadbord" it and your comments about sound (possible comparisons with "Merlin"?). I noticed that you didn`t use "stoppers" on g2 and 2A3 input - not necessary?
For HV 15pF cap - maybe three 47pF in series (standard value)?
And 23kHz (w/o 15pF caps) means "lot" of Cw (with Zout~10k of the driver)?
