There are several possibilities. A low-current low-noise opamp, a single stage using BJT's, or a single stage using FET's. In the absence of any other info, the jury is open. All these are capable of excellent performance with a magnetic pickup.Vikki said:Looking to build a preamp/buffer along the lines of the Sunrise magnetic acoustic pickup buffer box, can anyone guide me to a schematic that may be suitable. I think the sunrise buffer uses a opa 2132.

OK Abbey. I give up!

How do you do an excellent RIAA pickup for magnetic cartridge with a single BJT or FET ??
