Whatever you do, handle the PCB with extreme care as the tracks will lift at the slightest chance - they certainly do not like repeated component changes.
I also repeat for everyone's benefit, do not under any circumstances bend the component leads hard over against the PCB tracks before soldering as you will curse yourself to hell when you come to exchange/replace a component later on, 5-10º is more than adequate, after all this is Hi Fi not rocket science
Space all high power resistors well away from the PCB especially the EL34 cathode bias resistors and the like.
