Single bjt (or fet) buffer schematic kindly requested.

[beppe61]

Dear Friends,

I am here to ask kindly for assistance.
I am looking for a complete schematic of a buffer based on just one bjt (or fet) with a single voltage power supply (24V possibly).
I looked at the articles in Erno Borbely great web site, but the one fet buffer proposed needs of a dual voltage power supply (+/-24 V).
The buffer should have very low output impedance, possibly 100-200 ohm and it should be able to drive properly a power amp with a very low input impedance (5kohm).

Needless to say that any help and suggestion would be very much appreciated.

Thank you very much indeed to everyone.

Kind regards,
