Tr for Schopeps circuit?

[ricren]

Hi folks,

I'm building some 48V phantom power to electrec mic adapters based in the Schopes circuit and I'm looking for the lowes noise transistor for the emiter followers. In the origiinal circuit they use BC 416C. Can someone recommend a good low noise transistor with Vce>48 volts?

Tks in advance for any info on this.

I was using with good results BC560 and also 2SA1349 monolithic pair in Schoeps circuit.

Tks for your reply.The monolitic dual transistor sound like a good idea-no need to match the pair.
I went to DigiKey and Mouser (my usual surces) but I can not found the 2SA part. Can you sugest a provider?

Also try B&D Enterprises. A great place for small quantities of the Japanese transistors.
