Pre-amplifer for magnetic phono pick-up.

[ppppenguin]

For a moving coil cartridge it's almost impossible without a transformer. Quad and others got good results with moving magnet cartridges such as the Shure M75 series mentioend above. Having said that, a Shure M75 of any kind isn't the ideal thing to stick in a SP25 whose pickup arm isn't good enough for the cartridge. Depends a bit on the stylus. A 75ED would be hopeless, a 75EJ might be OK. For a magnetic cartridge in a SP25 think about a Shure M44 or a Goldring G800.

Just go solid state, you know it makes sense.
