Somewhere there is a thread on my RIAA preamplifier. I found the EF86 stage used in the valve pre-amplifier I was using was noisy and a bit short on gain and ended up with a twin triode phono stage. If you are building a stereo 3-3 it's worth upgrading the mains transformer/PSU section to power other accessories you might want to add.
