Line preamp for 2A3 amp


Can someone tell me where can i find a *simple* line preamp for driving an Elektor based schematic of a 2A3 amp (in zur Linde's book)? They say it needs 2V in. I have a preamp schematic from Pat's schematics (one of his designs) but don't know if it is ok. It has 15dB out an uses 5687 tubes.

Thank you for all the help
