Default Re: Ceramic cartridge preamps revisited

I didn't sim, honest !

ac gain R4/R5
dc gain R4/(R5+R6)

T2 could be anything with lots of gain as its doing most of the work, if you ignore the the input impedance! (which probably could be a lot more that 1M with suitable R2)

It looks quite neat to me.
Is 1M a standard ?

dc
