I use my edison with meridian 502 pre

Nothing oddball with this one!

This is from famous Audion and Audio Innovations designer Erik Andersson. The reason for the high gain was that it should be used with a passive preamp. This was called Edison 1 and had a good RIAA stage together with the passive line.

Very good special design OPTs.
