Hi!

Stefano just made me aware about this forum, so I registered. Interesting thread about LCR RIAAs, one of my favorite topics :-)

About the gain of the WE437 phono: Since Stefano wants to use external MC step ups, I designed the phonostage for MM sensitivity. Still it has quite a lot of gain to match up with his line sources. The phono stage has approximately 46-48 dB of gain (would need to measure it to get the exact figure). My own version of the very same preamp using the EC8020 has a built in MC-step up (Lundahl LL1933, 1:16). The phono stage has a low output impedance. If needed it could drive a step up inut transformer in the linestage. I left out the step up in Stefanos line stage since he has quite senistive power amps and usually listens at moderate levels. This way he has a sensible range on the volume control (Slagle TVC). If needed the line stage could be equipped with a 1:4 or 1:8 step up. In my own line stage I have one of the inputs with such a step up to be prepared for all gain needs.

Best regards

Thomas
