Am I wrong when I think that MC pickups (cartridges) use all 4 tubes? The two middle ones (in C2500) to boost the weak MC signal to MM strength and then the two on the left also used by MM pickups. The latter is the RIAA amplifier. Otherwise how would you make the RIAA correction when using MC pickups?
Edit: Had a look at the diagram on top of the C2500 and it seems I was wrong. I guess it means the amplifier must have two parallel RIAA correction stages?
