Don't like to toot my own horn but I published a DIY phono stage, based on JC Morrison's design from Sound Practices No. 3 and 4, in AudioXpress in January and February 2004. The mods to the audio circuitry consisted of a much better RIAA EQ (within 0.1 dB of ideal) and substituting a 6J5 third stage for the 6N7 or 7F8 tube originally specified, plus a choke power supplies for B+, filament and first stage constant current source. B+ supply used damper diodes for rectification. Sounds good to me but of course I'm biased.
