Hi Ian,

I'm planning to power it up after my holidays, it look like it could have some potential.

It has a interesting phonostage with a BC107 and half of a ECC83, in the late seventies I built a very similar design using a fet instead of a transistor this feed into a EF86 connected in triode mode.
The fet and the EF86 work well and I prefered it to the fet and ECC83, I felt that something was lost when using the ECC83 in that it wasn't as detail as the EF86.
One thing I don't like is the sound of a ECC83 cathode follower as is in the output stage of the Radford SC22. I will probably redesign it with a ECC88 or a mosfet.

Watch out for the Radford SC22 Preamp Challenge!

Sharif.
