Well, I have no experience with this model (SS/tube hibrid preamp, tube PP EL84 output), nor I`m the professional - but this is my "general" opinion/experience abot the mods. In almost every old amp I checked/repaired (for myself or the friends), somebody soldered some clever tricks. For example - tube rectifier to SS, additional gain stage, master volume, changed various parts to the non-original specifications (from resistors and capacitors to transformers and tubes), decreased/disconnected NFB loop, bias balance pot to bias "range" pot, switches, line-out...
IMO- most of this just ruined the originality/sound, and in some cases ruined amp functionality/stability (oscillations). There ARE some good thought out mods from the people who really know what they are doing, but my opinion is - if it works good, then don`t fix it 
"You electricians think you`re so cool. Then you die."
