As my intention was always to create a useful working piece of equipment I was going to need a preamplifier suitable for use with modern sources - OK maybe LPs aren't considered modern any longer.
The solution was to build a stereo pre-amplifier to the 1950s Mullard design, but subsituting 1930s style octal valves for the 1950s 9 pin EF86s. Plus I needed to add a phase splitter. Six of the the excellent EF37A made a quality pre-amp. Now I just need to complete the cabinet.
