Cranky what is input impedance ? (searched the net but it is confusing) Ceramic cartridges produces good enough voltage so no need of pre amp right ? Sorry I am new to technical things but it is good to acquire knowledge.a preamp only need provide a high enough input impedance and a very small amount of gain, 6 (x2) or 10 (x3) dB should be good
so it is good for 78 rpm discs but 45s and 33s require equilisation so can Rajeev put some resistor and use this preamp+RIAA Eq. circuit ?
